     <p><strong>CoffeeScript is a little language that compiles into JavaScript.</strong> Underneath that awkward Java-esque patina, JavaScript has always had a gorgeous heart. CoffeeScript is an attempt to expose the good parts of JavaScript in a simple way.</p>
 <p>The golden rule of CoffeeScript is: <em>“It’s just JavaScript”</em>. The code compiles one-to-one into the equivalent JS, and there is no interpretation at runtime. You can use any existing JavaScript library seamlessly from CoffeeScript (and vice-versa). The compiled output is readable, pretty-printed, and tends to run as fast or faster than the equivalent handwritten JavaScript.</p>
 <p>The CoffeeScript compiler goes to great lengths to generate output JavaScript that runs in every JavaScript runtime, but there are exceptions. Use <a href="#generator-functions">generator functions</a>, <a href="#generator-iteration"><code>for…from</code></a>, or <a href="#tagged-template-literals">tagged template literals</a> only if you know that your <a href="http://kangax.github.io/compat-table/es6/">target runtimes can support them</a>.

(Sorry they couldn’t match, but we came up with <code>for…of</code> first for something else.) This allows iterating over generators or any other iterable object. Note that using <code>for…from</code> in your code makes you responsible for ensuring that either your runtime supports <code>for…of</code> or that you transpile the output JavaScript further to a version your target runtime(s) support.</li>
 <li>Triple backticks (<code>```​</code>) allow the creation of embedded JavaScript blocks where escaping single backticks is not required, which should improve interoperability with ES2015 template literals and with Markdown.</li>

+              <p>The CoffeeScript option parser is a little odd; options after the first
+non-option argument are treated as non-option arguments themselves.
+Optional arguments are normalized by expanding merged flags into multiple
+flags. This allows you to have <code>-wl</code> be the same as <code>--watch --lint</code>.
+Note that executable scripts with a shebang (<code>#!</code>) line should use the
+line <code>#!/usr/bin/env coffee</code>, or <code>#!/absolute/path/to/coffee</code>, without a
+<code>--</code> argument after, because that will fail on Linux (see #3946).</p>

+<p>We are pleased to announce CoffeeScript 2! This new release of the CoffeeScript language and compiler aims to bring CoffeeScript into the modern JavaScript era, closing gaps in compatibility with JavaScript while preserving the clean syntax that is CoffeeScript’s hallmark. In a nutshell:</p>
+<ul>
+<li>The CoffeeScript 2 compiler now translates CoffeeScript code into modern JavaScript syntax. So a CoffeeScript <code>=&gt;</code> is now output as <code>=&gt;</code>, a CoffeeScript <code>class</code> is now output using the <code>class</code> keyword, and so on. This means you may need to <a href="../#transpilation">transpile the CoffeeScript compiler’s output</a>.</li>
+<li>CoffeeScript 2 adds support for <a href="../#async-functions">async functions</a> syntax, for the future <a href="../#destructuring">object destructuring</a> syntax, and for <a href="../#jsx">JSX</a>. Some features, such as <a href="../#modules">modules</a> (<code>import</code> and <code>export</code> statements), <a href="../#generator-iteration"><code>for…of</code></a>, and <a href="../#tagged-template-literals">tagged template literals</a> were backported into CoffeeScript versions 1.11 and 1.12.</li>
+<li>All of the above was achieved with very few <a href="../#breaking-changes">breaking changes from 1.x</a>. Most current CoffeeScript projects should be able to upgrade with little or no refactoring necessary.</li>
+</ul>
+<p>CoffeeScript 2 was developed with two primary goals: remove any incompatibilities with modern JavaScript that might prevent CoffeeScript from being used on a project; and preserve as much backward compatibility as possible. <a href="../#installation">Install now</a>: <code>npm install -g coffeescript@2</code></p>
+<h2 id="modern-javascript-output">Modern JavaScript Output</h2>
+<p>From the beginning, CoffeeScript has been described as being “just JavaScript.” And today, JavaScript is ES2015 (well, ES2017; also commonly known as ES6). CoffeeScript welcomes the changes in the JavaScript world and we’re happy to stop outputting circa-1999 syntax for modern features.</p>
+<p>Many new JavaScript features, such as <code>=&gt;</code>, were informed by CoffeeScript and are one-to-one compatible, or very nearly so. This has made outputting many of CoffeeScript’s innovations into new JS syntax straightforward: not only does <code>=&gt;</code> become <code>=&gt;</code>, but <code>{ a } = obj</code> becomes <code>{ a } = obj</code>, <code>&quot;a#{b}c&quot;</code> becomes <code>`a${b}c`</code> and so on.</p>
+<p>The following CoffeeScript features were updated in 2.0 to output using modern JavaScript syntax (or added in CoffeeScript 1.11 through 2.0, output using modern syntax):</p>
+<ul>
+<li>Modules: <code>import</code>/<code>export</code></li>
+<li>Classes: <code>class Animal</code></li>
+<li>Async functions: <code>await someFunction()</code></li>
+<li>Bound/arrow functions: <code>=&gt;</code></li>
+<li>Function default parameters: <code>(options = {}) -&gt;</code></li>
+<li>Function splat/rest parameters: <code>(items...) -&gt;</code></li>
+<li>Destructuring, for both arrays and objects: <code>[first, second] = items</code>, <code>{length} = items</code></li>
+<li>Object rest/spread properties: <code>{options..., force: yes}</code>, <code>{force, otherOptions...} = options</code></li>
+<li>Interpolated strings/template literals (JS backticked strings): <code>&quot;Hello, #{user}!&quot;</code></li>
+<li>Tagged template literals: <code>html&quot;&lt;strong&gt;coffee&lt;/strong&gt;&quot;</code></li>
+<li>JavaScript’s <code>for…of</code> is now available as CoffeeScript’s <code>for…from</code> (we already had a <code>for…of</code>): <code>for n from generatorFunction()</code></li>
+</ul>
+<p>Not all CoffeeScript features were adopted into JavaScript in 100% the same way; most notably, <a href="../#breaking-changes-default-values">default values</a> in JavaScript (and also in CoffeeScript 2) are only applied when a variable is <code>undefined</code>, not <code>undefined</code> or <code>null</code> as in CoffeeScript 1; and <a href="../#breaking-changes-classes">classes</a> have their own differences. See the <a href="../#breaking-changes">breaking changes</a> for the fine details.</p>
+<p>In our experience, most breaking changes are edge cases that should affect very few people, like JavaScript’s <a href="../#breaking-change-fat-arrow">lack of an <code>arguments</code> object inside arrow functions</a>. There seem to be two breaking changes that affect a significant number of projects:</p>
+<ul>
+<li>In CoffeeScript 2, “bare” <code>super</code> (calling <code>super</code> without arguments) is now no longer allowed, and one must use <code>super()</code> or <code>super arguments...</code> instead.</li>
+<li>References to <code>this</code>/<code>@</code> cannot occur before a call to <code>super</code>, per the JS spec.</li>
+</ul>
+<p>See the <a href="../#breaking-changes-super-extends">full details</a>. Either the CoffeeScript compiler or your transpiler will throw errors for either of these cases, so updating your code is a matter of fixing each occurrence as the compiler errors on it, until your code compiles successfully.</p>
+<h2 id="other-features">Other Features</h2>
+<p>Besides supporting new JavaScript features and outputting older CoffeeScript features in modern JS syntax, CoffeeScript 2 has added support for the following:</p>
+<ul>

+<h2 id="what-about-…">“What About …?”</h2>
+<p>A few JavaScript features have been intentionally omitted from CoffeeScript. These include <code>let</code> and <code>const</code> (and <code>var</code>), named functions and the <code>get</code> and <code>set</code> keywords. These get asked about so often that we added a section to the docs called <a href="../#unsupported">Unsupported ECMAScript Features</a>. CoffeeScript’s lack of equivalents for these features does not affect compatibility or interoperability with JavaScript modules or libraries.</p>
+<h2 id="future-compatibility">Future Compatibility</h2>
+<p>Back when CoffeeScript 1 was created, ES2015 JavaScript and transpilers like <a href="http://babeljs.io/">Babel</a>, <a href="https://buble.surge.sh/">Bublé</a> or <a href="https://github.com/google/traceur-compiler">Traceur Compiler</a> were several years away. The CoffeeScript compiler itself had to do what today’s transpilers do, converting modern features like destructuring and arrow functions into equivalent lowest-common-denominator JavaScript.</p>
+<p>But transpilers exist now, and they do their job well. With them around, there’s no need for the CoffeeScript compiler to duplicate this functionality. All the CoffeeScript compiler needs to worry about now is converting the CoffeeScript version of new syntax into the JS version of that syntax, e.g. <code>&quot;Hello, #{name}!&quot;</code> into <code>`Hello, ${name}!`</code>. This makes adding support for new JavaScript features much easier than before.</p>
+<p>Most features added by ECMA in recent years haven’t required any updates at all in CoffeeScript. New global objects, or new methods on global objects, don’t require any updates on CoffeeScript’s part to work. Some proposed future JS features <em>do</em> involve new syntax, like <a href="https://github.com/tc39/proposal-class-fields">class fields</a>. We have adopted a policy of supporting new syntax only when it reaches Stage 4 in ECMA’s process, which means that the syntax is final and will be in the next ES release. On occasion we might support a <em>feature</em> before it has reached Stage 4, but output it using equivalent non-experimental syntax instead of the newly-proposed syntax; that’s what’s happening in 2.0.0 for <a href="../#splats">object destructuring</a>, where our output uses the same polyfill that Babel uses. When the new syntax is finalized, we will update our output to use the final syntax.</p>
+<h2 id="credits">Credits</h2>
+<p>The major features of 2.0.0 would not have been possible without the following people:</p>

+# Announcing CoffeeScript 2
+
+We are pleased to announce CoffeeScript 2! This new release of the CoffeeScript language and compiler aims to bring CoffeeScript into the modern JavaScript era, closing gaps in compatibility with JavaScript while preserving the clean syntax that is CoffeeScript’s hallmark. In a nutshell:
+
+- The CoffeeScript 2 compiler now translates CoffeeScript code into modern JavaScript syntax. So a CoffeeScript `=>` is now output as `=>`, a CoffeeScript `class` is now output using the `class` keyword, and so on. This means you may need to [transpile the CoffeeScript compiler’s output](../#es2015plus-output).
+- CoffeeScript 2 adds support for [async functions](../#async-functions) syntax, for the future [object destructuring](../#destructuring) syntax, and for [JSX](../#jsx). Some features, such as [modules](../#modules) (`import` and `export` statements), [`for…of`](../#generator-iteration), and [tagged template literals](../#tagged-template-literals) were backported into CoffeeScript versions 1.11 and 1.12.
+- All of the above was achieved with very few [breaking changes from 1.x](../#breaking-changes). Most current CoffeeScript projects should be able to upgrade with little or no refactoring necessary.
+
+CoffeeScript 2 was developed with two primary goals: remove any incompatibilities with modern JavaScript that might prevent CoffeeScript from being used on a project; and preserve as much backward compatibility as possible. [Install now](../#installation): `npm install -g coffeescript@2`
+
+## Modern JavaScript Output
+
+From the beginning, CoffeeScript has been described as being “just JavaScript.” And today, JavaScript is ES2015 (well, ES2017; also commonly known as ES6). CoffeeScript welcomes the changes in the JavaScript world and we’re happy to stop outputting circa-1999 syntax for modern features.
+
+Many new JavaScript features, such as `=>`, were informed by CoffeeScript and are one-to-one compatible, or very nearly so. This has made outputting many of CoffeeScript’s innovations into new JS syntax straightforward: not only does `=>` become `=>`, but `{ a } = obj` becomes `{ a } = obj`, `"a#{b}c"` becomes `` `a${b}c` `` and so on.
+
+The following CoffeeScript features were updated in 2.0 to output using modern JavaScript syntax (or added in CoffeeScript 1.11 through 2.0, output using modern syntax):
+
+- Modules: `import`/`export`
+- Classes: `class Animal`
+- Async functions: `await someFunction()`
+- Bound/arrow functions: `=>`
+- Function default parameters: `(options = {}) ->`
+- Function splat/rest parameters: `(items...) ->`
+- Destructuring, for both arrays and objects: `[first, second] = items`, `{length} = items`
+- Object rest/spread properties: `{options..., force: yes}`, `{force, otherOptions...} = options`
+- Interpolated strings/template literals (JS backticked strings): `"Hello, #{user}!"`
+- Tagged template literals: `html"<strong>coffee</strong>"`
+- JavaScript’s `for…of` is now available as CoffeeScript’s `for…from` (we already had a `for…of`): `for n from generatorFunction()`
+
+Not all CoffeeScript features were adopted into JavaScript in 100% the same way; most notably, [default values](../#breaking-changes-default-values) in JavaScript (and also in CoffeeScript 2) are only applied when a variable is `undefined`, not `undefined` or `null` as in CoffeeScript 1; and [classes](../#breaking-changes-classes) have their own differences. See the [breaking changes](../#breaking-changes) for the fine details.
+
+In our experience, most breaking changes are edge cases that should affect very few people, like JavaScript’s [lack of an `arguments` object inside arrow functions](../#breaking-change-fat-arrow). There seem to be two breaking changes that affect a significant number of projects:
+
+- In CoffeeScript 2, “bare” `super` (calling `super` without arguments) is now no longer allowed, and one must use `super()` or `super arguments...` instead.
+- References to `this`/`@` cannot occur before a call to `super`, per the JS spec.
+
+See the [full details](../#breaking-changes-super-extends). Either the CoffeeScript compiler or your transpiler will throw errors for either of these cases, so updating your code is a matter of fixing each occurrence as the compiler errors on it, until your code compiles successfully.
+
+## Other Features
+
+Besides supporting new JavaScript features and outputting older CoffeeScript features in modern JS syntax, CoffeeScript 2 has added support for the following:
+
+- [JSX](../#jsx)
+- [Line comments](../#comments) are now output (in CoffeeScript 1 they were discarded)
+- Block comments are now allowed anywhere, enabling [static type annotations](../#type-annotations) using Flow’s comment-based syntax
+
+There are many smaller improvements as well, such as to the `coffee` command-line tool. You can read all the details in the [changelog](../#changelog) for the 2.0.0 betas.
+
+## “What About …?”
+
+A few JavaScript features have been intentionally omitted from CoffeeScript. These include `let` and `const` (and `var`), named functions and the `get` and `set` keywords. These get asked about so often that we added a section to the docs called [Unsupported ECMAScript Features](../#unsupported). CoffeeScript’s lack of equivalents for these features does not affect compatibility or interoperability with JavaScript modules or libraries.
+
+## Future Compatibility
+
+Back when CoffeeScript 1 was created, ES2015 JavaScript and transpilers like [Babel](http://babeljs.io/), [Bublé](https://buble.surge.sh/) or [Traceur Compiler](https://github.com/google/traceur-compiler) were several years away. The CoffeeScript compiler itself had to do what today’s transpilers do, converting modern features like destructuring and arrow functions into equivalent lowest-common-denominator JavaScript.
+
+But transpilers exist now, and they do their job well. With them around, there’s no need for the CoffeeScript compiler to duplicate this functionality. All the CoffeeScript compiler needs to worry about now is converting the CoffeeScript version of new syntax into the JS version of that syntax, e.g. `"Hello, #{name}!"` into `` `Hello, ${name}!` ``. This makes adding support for new JavaScript features much easier than before.
+
+Most features added by ECMA in recent years haven’t required any updates at all in CoffeeScript. New global objects, or new methods on global objects, don’t require any updates on CoffeeScript’s part to work. Some proposed future JS features _do_ involve new syntax, like [class fields](https://github.com/tc39/proposal-class-fields). We have adopted a policy of supporting new syntax only when it reaches Stage 4 in ECMA’s process, which means that the syntax is final and will be in the next ES release. On occasion we might support a _feature_ before it has reached Stage 4, but output it using equivalent non-experimental syntax instead of the newly-proposed syntax; that’s what’s happening in 2.0.0 for [object destructuring](../#splats), where our output uses the same polyfill that Babel uses. When the new syntax is finalized, we will update our output to use the final syntax.
+

+### Bound (fat arrow) functions
+
+In CoffeeScript 1.x, `=>` compiled to a regular `function` but with references to `this`/`@` rewritten to use the outer scope’s `this`, or with the inner function bound to the outer scope via `.bind` (hence the name “bound function”). In CoffeeScript 2, `=>` compiles to [ES2015’s `=>`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions), which behaves slightly differently. The largest difference is that in ES2015, `=>` functions lack an `arguments` object:

+### Argument parsing and shebang (`#!`) lines
+
+In CoffeeScript 1.x, `--` was required after the path and filename of the script to be run, but before any arguments passed to that script. This convention is now deprecated. So instead of:
+
+```bash
+coffee [options] path/to/script.coffee -- [args]
+```
+
+Now you would just type:
+
+```bash
+coffee [options] path/to/script.coffee [args]
+```
+
+The deprecated version will still work, but it will print a warning before running the script.
+
+On non-Windows platforms, a `.coffee` file can be made executable by adding a shebang (`#!`) line at the top of the file and marking the file as executable. For example:
+
+```coffee
+#!/usr/bin/env coffee
+
+x = 2 + 2
+console.log x
+```
+
+If this were saved as `executable.coffee`, it could be made executable and run:
+
+```bash
+▶ chmod +x ./executable.coffee
+▶ ./executable.coffee
+4
+```
+
+In CoffeeScript 1.x, this used to fail when trying to pass arguments to the script. Some users on OS X worked around the problem by using `#!/usr/bin/env coffee --` as the first line of the file. That didn’t work on Linux, however, which cannot parse shebang lines with more than a single argument. While such scripts will still run on OS X, CoffeeScript will now display a warning before compiling or evaluating files that begin with a too-long shebang line. Now that CoffeeScript 2 supports passing arguments without needing `--`, we recommend simply changing the shebang lines in such scripts to just `#!/usr/bin/env coffee`.

+### JSX and the `<` and `>` operators
+
+With the addition of [JSX](#jsx), the `<` and `>` characters serve as both the “less than” and “greater than” operators and as the delimiters for XML tags, like `<div>`. For best results, in general you should always wrap the operators in spaces to distinguish them from XML tags: `i < len`, not `i<len`. The compiler tries to be forgiving when it can be sure what you intend, but always putting spaces around the “less than” and “greater than” operators will remove ambiguity.

+
+*   Bugfix to set the correct context for executable class bodies. So in `class @B extends @A then @property = 1`, the `@` in `@property` now refers to the class, not the global object.
+*   Bugfix where anonymous classes were getting created using the same automatic variable name. They now each receive unique names, so as not to override each other.
+
+

+*   Skipping of array elements, a.k.a. elision, is now supported: `arr = [a, , b]`, or `[, protocol] = url.match /^(.*):\/\//`.
+*   [JSX fragments syntax](https://reactjs.org/blog/2017/11/28/react-v16.2.0-fragment-support.html) is now supported.
+*   Bugfix where `///` within a `#` line comment inside a `///` block regex was erroneously closing the regex, rather than being treated as part of the comment.
+*   Bugfix for incorrect output for object rest destructuring inside array destructuring.
+
+```
+releaseHeader('2017-11-26', '2.0.3', '2.0.2')
+```
+
+*   Bugfix for `export default` followed by an implicit object that contains an explicit object, for example `exportedMember: { obj... }`.
+*   Bugfix for `key, val of obj` after an implicit object member, e.g. `foo: bar for key, val of obj`.
+*   Bugfix for combining array and object destructuring, e.g. `[ ..., {a, b} ] = arr`.
+*   Bugfix for an edge case where it was possible to create a bound (`=>`) generator function, which should throw an error as such functions aren’t allowed in ES2015.
+*   Bugfix for source maps: `.map` files should always have the same base filename as the requested output filename. So `coffee --map --output foo.js test.coffee` should generate `foo.js` and `foo.js.map`.
+*   Bugfix for incorrect source maps generated when using `--transpile` with `--map` for multiple input files.
+*   Bugfix for comments at the beginning or end of input into the REPL (`coffee --interactive`).
+
+```
+releaseHeader('2017-10-26', '2.0.2', '2.0.1')
+```
+*   `--transpile` now also applies to `require`d or `import`ed CoffeeScript files.
+*   `--transpile` can be used with the REPL: `coffee --interactive --transpile`.
+*   Improvements to comments output that should now cover all of the [Flow comment-based syntax](https://flow.org/en/docs/types/comments/). Inline `###` comments near [variable](https://flow.org/en/docs/types/variables/) initial assignments are now output in the variable declaration statement, and `###` comments near a [class and method names](https://flow.org/en/docs/types/generics/) are now output where Flow expects them.
+*   Importing CoffeeScript keywords is now allowed, so long as they’re aliased: `import { and as andFn } from 'lib'`. (You could also do `import lib from 'lib'` and then reference `lib.and`.)
+*   Calls to functions named `get` and `set` no longer throw an error when given a bracketless object literal as an argument: `obj.set propertyName: propertyValue`.
+*   In the constructor of a derived class (a class that `extends` another class), you cannot call `super` with an argument that references `this`: `class Child extends Parent then constructor: (@arg) -> super(@arg)`. This isn’t allowed in JavaScript, and now the CoffeeScript compiler will throw an error. Instead, assign to `this` after calling `super`: `(arg) -> super(arg); @arg = arg`.
+*   Bugfix for incorrect output when backticked statements and hoisted expressions were both in the same class body. This allows a backticked line like `` `field = 3` ``, for people using the experimental [class fields](https://github.com/tc39/proposal-class-fields) syntax, in the same class along with traditional class body expressions like `prop: 3` that CoffeeScript outputs as part of the class prototype.
+*   Bugfix for comments not output before a complex `?` operation, e.g. `@a ? b`.
+*   All tests now pass in Windows.
+

+releaseHeader('2017-09-26', '2.0.1', '2.0.0')

+
+*   `babel-core` is no longer listed in `package.json`, even as an `optionalDependency`, to avoid it being automatically installed for most users. If you wish to use `--transpile`, simply install `babel-core` manually. See [Transpilation](#transpilation).
+*   `--transpile` now relies on Babel to find its options, i.e. the `.babelrc` file in the path of the file(s) being compiled. (Previously the CoffeeScript compiler was duplicating this logic, so nothing has changed from a user’s perspective.) This provides automatic support for additional ways to pass options to Babel in future versions, such as the `.babelrc.js` file coming in Babel 7.
+*   Backticked expressions in a class body, outside any class methods, are now output in the JavaScript class body itself. This allows for passing through experimental JavaScript syntax like the [class fields proposal](https://github.com/tc39/proposal-class-fields), assuming your [transpiler supports it](https://babeljs.io/docs/plugins/transform-class-properties/).
+
+```
+releaseHeader('2017-09-18', '2.0.0', '2.0.0-beta5')
+```
+
+*   Added `--transpile` flag or `transpile` Node API option to tell the CoffeeScript compiler to pipe its output through Babel before saving or returning it; see [Transpilation](#transpilation). Also changed the `-t` short flag to refer to `--transpile` instead of `--tokens`.
+*   Always populate source maps’ `sourcesContent` property.
+*   Bugfixes for destructuring and for comments in JSX.
+*   _Note that these are only the changes between 2.0.0-beta5 and 2.0.0. See below for all changes since 1.x._

+
+*   Node 6 is now supported, and we will try to maintain that as the minimum required version for CoffeeScript 2 via the `coffee` command or Node API. Older versions of Node, or non-evergreen browsers, can compile via the [browser compiler](./browser-compiler/coffeescript.js).
+*   The command line `--output` flag now allows you to specify an output filename, not just an output folder.
+*   The command line `--require` flag now properly handles filenames or module names that are invalid identifiers (like an NPM module with a hyphen in the name).
+*   `Object.assign`, output when object destructuring is used, is polyfilled using the same polyfill that Babel outputs. This means that polyfills shouldn’t be required unless support for Internet Explorer 8 or below is desired (or your own code uses a feature that requires a polyfill). See [ES2015+ Output](#es2015plus-output).
+*   A string or JSX interpolation that contains only a comment (`"a#{### comment ###}b"` or `<div>{### comment ###}</div>`) is now output (`` `a${/* comment */}b` ``)
+*   Interpolated strings (ES2015 template literals) that contain quotation marks no longer have the quotation marks escaped: `` `say "${message}"` ``
+*   It is now possible to chain after a function literal (for example, to define a function and then call `.call` on it).
+*   The results of the async tests are included in the output when you run `cake test`.
+*   Bugfixes for object destructuring; expansions in function parameters; generated reference variables in function parameters; chained functions after `do`; splats after existential operator soaks in arrays (`[a?.b...]`); trailing `if` with splat in arrays or function parameters (`[a if b...]`); attempting to `throw` an `if`, `for`, `switch`, `while` or other invalid construct.
+*   Bugfixes for syntactical edge cases: semicolons after `=` and other “mid-expression” tokens; spaces after `::`; and scripts that begin with `:` or `*`.
+*   Bugfixes for source maps generated via the Node API; and stack trace line numbers when compiling CoffeeScript via the Node API from within a `.coffee` file.

 ## CoffeeScript 2
-
-### What’s New In CoffeeScript 2?
-
-The biggest change in CoffeeScript 2 is that now the CoffeeScript compiler produces modern, ES2015+ JavaScript. A CoffeeScript `=>` becomes an ES `=>`, a CoffeeScript `class` becomes an ES `class` and so on. With the exception of modules (`import` and `export` statements), all the ES2015+ features that CoffeeScript supports can run natively in Node 7.6+, meaning that Node can run CoffeeScript’s output without any further processing required. You can [run the tests in your browser](http://coffeescript.org/v<%= majorVersion %>/test.html) to see if your browser can do the same; Chrome has supported all features since version 55.
-
-Support for ES2015+ syntax is important to ensure compatibility with frameworks that assume ES2015. Now that CoffeeScript compiles classes to the ES `class` keyword, it’s possible to `extend` an ES class; that wasn’t possible in CoffeeScript 1. Parity in how language features work is also important on its own; CoffeeScript “is just JavaScript,” and so things like [function parameter default values](#breaking-changes-default-values) should behave the same in CoffeeScript as in JavaScript.
-
-Many ES2015+ features have been backported to CoffeeScript 1.11 and 1.12, including [modules](#modules), [`for…of`](#generator-iteration), and [tagged template literals](#tagged-template-literals). One major new feature unique to CoffeeScript 2 is support for ES2017’s [async functions](#async-functions). More details are in the [changelog](#changelog).
-
-There are very few [breaking changes from CoffeeScript 1.x to 2](#breaking-changes); we hope the upgrade process is smooth for most projects.
-
-### Why CoffeeScript When There’s ES2015?
-
-CoffeeScript introduced many new features to the JavaScript world, such as [`=>`](#fat-arrow) and [destructuring](#destructuring) and [classes](#classes). We are happy that ECMA has seen their utility and adopted them into ECMAScript.
-
-CoffeeScript’s intent, however, was never to be a superset of JavaScript. One of the guiding principles of CoffeeScript has been _simplicity:_ not just removing JavaScript’s “bad parts,” but providing an elegant, concise syntax that eschews unnecessary punctuation whenever possible, to make code easier to read and reason about. This benefit of CoffeeScript remains, even in an ES2015 world.

+### Command Line
+
+Once installed, you should have access to the `coffee` command, which can execute scripts, compile `.coffee` files into `.js`, and provide an interactive REPL. The `coffee` command takes the following options:
+
+| Option | Description |
+| --- | --- |
+| `-c, --compile` | Compile a `.coffee` script into a `.js` JavaScript file of the same name. |
+| `-t, --transpile` | Pipe the CoffeeScript compiler’s output through Babel before saving or running the generated JavaScript. Requires `babel-core` to be installed, and options to pass to Babel in a `.babelrc` file or a `package.json` with a `babel` key in the path of the file or folder to be compiled. See [Transpilation](#transpilation).
+| `-m, --map` | Generate source maps alongside the compiled JavaScript files. Adds `sourceMappingURL` directives to the JavaScript as well. |
+| `-M, --inline-map` | Just like `--map`, but include the source map directly in the compiled JavaScript files, rather than in a separate file. |
+| `-i, --interactive` | Launch an interactive CoffeeScript session to try short snippets. Identical to calling `coffee` with no arguments. |
+| `-o, --output [DIR]` | Write out all compiled JavaScript files into the specified directory. Use in conjunction with `--compile` or `--watch`. |
+| `-w, --watch` | Watch files for changes, rerunning the specified command when any file is updated. |
+| `-p, --print` | Instead of writing out the JavaScript as a file, print it directly to **stdout**. |
+| `-s, --stdio` | Pipe in CoffeeScript to STDIN and get back JavaScript over STDOUT. Good for use with processes written in other languages. An example:<br>`cat src/cake.coffee | coffee -sc` |
+| `-l, --literate` | Parses the code as Literate CoffeeScript. You only need to specify this when passing in code directly over **stdio**, or using some sort of extension-less file name. |
+| `-e, --eval` | Compile and print a little snippet of CoffeeScript directly from the command line. For example:<br>`coffee -e "console.log num for num in [10..1]"` |
+| `-r, --require [MODULE]`&emsp; | `require()` the given module before starting the REPL or evaluating the code given with the `--eval` flag. |
+| `-b, --bare` | Compile the JavaScript without the [top-level function safety wrapper](#lexical-scope). |
+| `--no-header` | Suppress the “Generated by CoffeeScript” header. |
+| `--nodejs` | The `node` executable has some useful options you can set, such as `--debug`, `--debug-brk`, `--max-stack-size`, and `--expose-gc`. Use this flag to forward options directly to Node.js. To pass multiple flags, use `--nodejs` multiple times. |
+| `--tokens` | Instead of parsing the CoffeeScript, just lex it, and print out the token stream. Used for debugging the compiler. |
+| `-n, --nodes` | Instead of compiling the CoffeeScript, just lex and parse it, and print out the parse tree. Used for debugging the compiler. |
+
+#### Examples:
+
+*   Compile a directory tree of `.coffee` files in `src` into a parallel tree of `.js` files in `lib`:<br>
+    `coffee --compile --output lib/ src/`
+*   Watch a file for changes, and recompile it every time the file is saved:<br>
+    `coffee --watch --compile experimental.coffee`
+*   Concatenate a list of files into a single script:<br>
+    `coffee --join project.js --compile src/*.coffee`
+*   Print out the compiled JS from a one-liner:<br>
+    `coffee -bpe "alert i for i in [0..10]"`
+*   All together now, watch and recompile an entire project as you work on it:<br>
+    `coffee -o lib/ -cw src/`
+*   Start the CoffeeScript REPL (`Ctrl-D` to exit, `Ctrl-V`for multi-line):<br>
+    `coffee`
+
+To use `--transpile`, see [Transpilation](#transpilation).

+## JSX
+
+[JSX](https://facebook.github.io/react/docs/introducing-jsx.html) is JavaScript containing interspersed XML elements. While conceived for [React](https://facebook.github.io/react/), it is not specific to any particular library or framework.
+
+CoffeeScript supports interspersed XML elements, without the need for separate plugins or special settings. The XML elements will be compiled as such, outputting JSX that could be parsed like any normal JSX file, for example by [Babel with the React JSX transform](https://babeljs.io/docs/plugins/transform-react-jsx/). CoffeeScript does _not_ output `React.createElement` calls or any code specific to React or any other framework. It is up to you to attach another step in your build chain to convert this JSX to whatever function calls you wish the XML elements to compile to.
+
+Just like in JSX and HTML, denote XML tags using `<` and `>`. You can interpolate CoffeeScript code inside a tag using `{` and `}`. To avoid compiler errors, when using `<` and `>` to mean “less than” or “greater than,” you should wrap the operators in spaces to distinguish them from XML tags. So `i < len`, not `i<len`. The compiler tries to be forgiving when it can be sure what you intend, but always putting spaces around the “less than” and “greater than” operators will remove ambiguity.
+
+```
+codeFor('jsx')
+```
+
+Older plugins or forks of CoffeeScript supported JSX syntax and referred to it as CSX or CJSX. They also often used a `.cjsx` file extension, but this is no longer necessary; regular `.coffee` will do.

+
+* `options.sourceMap`, boolean: if true, a source map will be generated; and instead of returning a string, `compile` will return an object of the form `{js, v3SourceMap, sourceMap}`.
+* `options.inlineMap`, boolean: if true, output the source map as a base64-encoded string in a comment at the bottom.
+* `options.filename`, string: the filename to use for the source map. It can include a path (relative or absolute).

+### Transpilation
+
+CoffeeScript 2 generates JavaScript that uses the latest, modern syntax. The runtime or browsers where you want your code to run [might not support all of that syntax](#compatibility). In that case, we want to convert modern JavaScript into older JavaScript that will run in older versions of Node or older browsers; for example, `{ a } = obj` into `a = obj.a`. This is done via transpilers like [Babel](http://babeljs.io/), [Bublé](https://buble.surge.sh/) or [Traceur Compiler](https://github.com/google/traceur-compiler).
+
+#### Quickstart
+
+From the root of your project:
+
+```bash
+npm install --save-dev babel-core babel-preset-env
+echo '{ "presets": ["env"] }' > .babelrc
+coffee --compile --transpile --inline-map some-file.coffee
+```
+
+#### Transpiling with the CoffeeScript compiler
+
+To make things easy, CoffeeScript has built-in support for the popular [Babel](http://babeljs.io/) transpiler. You can use it via the `--transpile` command-line option or the `transpile` Node API option. To use either, `babel-core` must be installed in your project:
+
+```bash
+npm install --save-dev babel-core
+```
+
+Or if you’re running the `coffee` command outside of a project folder, using a globally-installed `coffeescript` module, `babel-core` needs to be installed globally:
+
+```bash
+npm install --global babel-core
+```
+
+By default, Babel doesn’t do anything—it doesn’t make assumptions about what you want to transpile to. You need to provide it with a configuration so that it knows what to do. One way to do this is by creating a [`.babelrc` file](https://babeljs.io/docs/usage/babelrc/) in the folder containing the files you’re compiling, or in any parent folder up the path above those files. (Babel supports [other ways](https://babeljs.io/docs/usage/babelrc/), too.) A minimal `.babelrc` file would be just `{ "presets": ["env"] }`. This implies that you have installed [`babel-preset-env`](https://babeljs.io/docs/plugins/preset-env/):
+
+```bash
+npm install --save-dev babel-preset-env  # Or --global for non-project-based usage
+```
+
+See [Babel’s website to learn about presets and plugins](https://babeljs.io/docs/plugins/) and the multitude of options you have. Another preset you might need is [`transform-react-jsx`](https://babeljs.io/docs/plugins/transform-react-jsx/) if you’re using JSX with React (JSX can also be used with other frameworks).
+
+Once you have `babel-core` and `babel-preset-env` (or other presets or plugins) installed, and a `.babelrc` file (or other equivalent) in place, you can use `coffee --transpile` to pipe CoffeeScript’s output through Babel using the options you’ve saved.
+
+If you’re using CoffeeScript via the [Node API](nodejs_usage), where you call `CoffeeScript.compile` with a string to be compiled and an `options` object, the `transpile` key of the `options` object should be the Babel options:
+
+```js
+CoffeeScript.compile(code, {transpile: {presets: ['env']}})
+```
+
+You can also transpile CoffeeScript’s output without using the `transpile` option, for example as part of a build chain. This lets you use transpilers other than Babel, and it gives you greater control over the process. There are many great task runners for setting up JavaScript build chains, such as [Gulp](http://gulpjs.com/), [Webpack](https://webpack.github.io/), [Grunt](https://gruntjs.com/) and [Broccoli](http://broccolijs.com/).
+
+#### Polyfills
+
+Note that transpiling doesn’t automatically supply [polyfills](https://developer.mozilla.org/en-US/docs/Glossary/Polyfill) for your code. CoffeeScript itself will output [`Array.indexOf`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/indexOf) if you use the `in` operator, or destructuring or spread/rest syntax; and [`Function.bind`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/bind) if you use a bound (`=>`) method in a class. Both are supported in Internet Explorer 9+ and all more recent browsers, but you will need to supply polyfills if you need to support Internet Explorer 8 or below and are using features that would cause these methods to be output. You’ll also need to supply polyfills if your own code uses these methods or another method added in recent versions of JavaScript. One polyfill option is [`babel-polyfill`](https://babeljs.io/docs/usage/polyfill/), though there are many [other](https://hackernoon.com/polyfills-everything-you-ever-wanted-to-know-or-maybe-a-bit-less-7c8de164e423) [strategies](https://philipwalton.com/articles/loading-polyfills-only-when-needed/).

+coffee --bare --no-header --compile app.coffee && npm run flow
+```
+
+`--bare` and `--no-header` are important because Flow requires the first line of the file to be the comment `// @flow`. If you configure your build chain to compile CoffeeScript and pass the result to Flow in-memory, you can get better performance than this example; and a proper build tool should be able to watch your CoffeeScript files and recompile and type-check them for you on save.
+
+If you know of another way to achieve static type checking with CoffeeScript, please [create an issue](https://github.com/jashkenas/coffeescript/issues/new) and let us know.

 Newcomers to CoffeeScript often wonder how to generate the JavaScript `function foo() {}`, as opposed to the `foo = function() {}` that CoffeeScript produces. The first form is a [function declaration](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/function), and the second is a [function expression](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/function). As stated above, in CoffeeScript [everything is an expression](#expressions), so naturally we favor the expression form. Supporting only one variant helps avoid confusing bugs that can arise from the [subtle differences between the two forms](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/function#Function_declaration_hoisting).
 
-Technically, `foo = function() {}` is creating an anonymous function that gets assigned to a variable named `foo`. Some very early versions of CoffeeScript named this function, e.g. `foo = function foo() {}`, but this was dropped because of compatibility issues with Internet Explorer. For a while this annoyed people, as these functions would be unnamed in stack traces; but modern JavaScript runtimes [infer the names of such anonymous functions](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/name) from the names of the variables to which they’re assigned. Given that this is the case, and given that not all functions in function expressions can be named (for example, the functions in `first.fn = ->; second.fn = ->` can’t both be named `fn`) it’s simplest to just preserve the current behavior.

 ## Usage
-
-Once installed, you should have access to the `coffee` command, which can execute scripts, compile `.coffee` files into `.js`, and provide an interactive REPL. The `coffee` command takes the following options:
-
-| Option | Description |
-| --- | --- |
-| `-c, --compile` | Compile a `.coffee` script into a `.js` JavaScript file of the same name. |
-| `-m, --map` | Generate source maps alongside the compiled JavaScript files. Adds `sourceMappingURL` directives to the JavaScript as well. |
-| `-M, --inline-map` | Just like `--map`, but include the source map directly in the compiled JavaScript files, rather than in a separate file. |
-| `-i, --interactive` | Launch an interactive CoffeeScript session to try short snippets. Identical to calling `coffee` with no arguments. |
-| `-o, --output [DIR]` | Write out all compiled JavaScript files into the specified directory. Use in conjunction with `--compile` or `--watch`. |
-| `-w, --watch` | Watch files for changes, rerunning the specified command when any file is updated. |
-| `-p, --print` | Instead of writing out the JavaScript as a file, print it directly to **stdout**. |
-| `-s, --stdio` | Pipe in CoffeeScript to STDIN and get back JavaScript over STDOUT. Good for use with processes written in other languages. An example:<br>`cat src/cake.coffee | coffee -sc` |
-| `-l, --literate` | Parses the code as Literate CoffeeScript. You only need to specify this when passing in code directly over **stdio**, or using some sort of extension-less file name. |
-| `-e, --eval` | Compile and print a little snippet of CoffeeScript directly from the command line. For example:<br>`coffee -e "console.log num for num in [10..1]"` |
-| `-r, --require [MODULE]`&emsp; | `require()` the given module before starting the REPL or evaluating the code given with the `--eval` flag. |
-| `-b, --bare` | Compile the JavaScript without the [top-level function safety wrapper](#lexical-scope). |
-| `-t, --tokens` | Instead of parsing the CoffeeScript, just lex it, and print out the token stream. Used for debugging the compiler. |
-| `-n, --nodes` | Instead of compiling the CoffeeScript, just lex and parse it, and print out the parse tree. Used for debugging the compiler. |
-| `--nodejs` | The `node` executable has some useful options you can set, such as `--debug`, `--debug-brk`, `--max-stack-size`, and `--expose-gc`. Use this flag to forward options directly to Node.js. To pass multiple flags, use `--nodejs` multiple times. |
-| `--no-header` | Suppress the “Generated by CoffeeScript” header. |
-
-### Examples:
-
-*   Compile a directory tree of `.coffee` files in `src` into a parallel tree of `.js` files in `lib`:<br>
-    `coffee --compile --output lib/ src/`
-*   Watch a file for changes, and recompile it every time the file is saved:<br>
-    `coffee --watch --compile experimental.coffee`
-*   Concatenate a list of files into a single script:<br>
-    `coffee --join project.js --compile src/*.coffee`
-*   Print out the compiled JS from a one-liner:<br>
-    `coffee -bpe "alert i for i in [0..10]"`
-*   All together now, watch and recompile an entire project as you work on it:<br>
-    `coffee -o lib/ -cw src/`
-*   Start the CoffeeScript REPL (`Ctrl-D` to exit, `Ctrl-V`for multi-line):<br>
-    `coffee`
-
-### ES2015+ Output
-
-CoffeeScript 2 outputs the latest ES2015+ syntax. If you’re looking for a single tool that takes CoffeeScript input and generates JavaScript output that runs in any JavaScript runtime, assuming you opt out of certain newer features, stick to [CoffeeScript 1.x](/v1/). CoffeeScript 2 [breaks compatibility](#breaking-changes) with certain CoffeeScript 1.x features in order to conform with the ES2015+ specifications, and generate more idiomatic output (a CoffeeScript `=>` becomes an ES `=>`; a CoffeeScript `class` becomes an ES `class`; and so on).
-
-Since the CoffeeScript 2 compiler outputs ES2015+ syntax, it is your responsibility to either ensure that your target JavaScript runtime(s) support all these features, or that you pass the output through another transpiler like [Babel](http://babeljs.io/), [Rollup](https://github.com/rollup/rollup) or [Traceur Compiler](https://github.com/google/traceur-compiler). In general, [CoffeeScript 2’s output is supported as is by Node.js 7.6+](http://node.green/), except for modules which require transpilation.
-
-There are many great task runners for setting up JavaScript build chains, such as [Gulp](http://gulpjs.com/), [Webpack](https://webpack.github.io/), [Grunt](https://gruntjs.com/) and [Broccoli](http://broccolijs.com/). If you’re looking for a very minimal solution to get started, you can use [babel-preset-env](https://babeljs.io/docs/plugins/preset-env/) and the command line:
-
-```bash
-npm install --global coffeescript@next
-npm install --save-dev coffeescript@next babel-cli babel-preset-env
-coffee -p *.coffee | babel --presets env > app.js
-```
-
-### Node.js
-
-If you’d like to use Node.js’ CommonJS to `require` CoffeeScript files, e.g. `require './app.coffee'`, you must first “register” CoffeeScript as an extension:
-
-```coffee
-require 'coffeescript/register'
-
-App = require './app' # The .coffee extension is optional
-```
-
-If you want to use the compiler’s API, for example to make an app that compiles strings of CoffeeScript on the fly, you can `require` the full module:
-
-```coffee
-CoffeeScript = require 'coffeescript'
-
-eval CoffeeScript.compile 'console.log "Mmmmm, I could really go for some #{Math.pi}"'
-```
-
-The `compile` method has the signature `compile(code, options)` where `code` is a string of CoffeeScript code, and the optional `options` is an object with some or all of the following properties:
-
-* `options.sourceMap`, boolean: if true, a source map will be generated; and instead of returning a string, `compile` will return an object of the form `{js, v3SourceMap, sourceMap}`.
-* `options.inlineMap`, boolean: if true, output the source map as a base64-encoded string in a comment at the bottom.
-* `options.filename`, string: the filename to use for the source map.
-* `options.bare`, boolean: if true, output without the [top-level function safety wrapper](#lexical-scope).
-* `options.header`, boolean: if true, output the `Generated by CoffeeScript` header.

+### What’s New In CoffeeScript 2?
+
+The biggest change in CoffeeScript 2 is that now the CoffeeScript compiler produces modern JavaScript syntax (ES6, or ES2015 and later). A CoffeeScript `=>` becomes a JS `=>`, a CoffeeScript `class` becomes a JS `class` and so on. Major new features in CoffeeScript 2 include [async functions](#async-functions) and [JSX](#jsx). You can read more in the [announcement](announcing-coffeescript-2/).
+
+There are very few [breaking changes from CoffeeScript 1.x to 2](#breaking-changes); we hope the upgrade process is smooth for most projects.
