<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>

### `super` and `this`
|
||||
|
||||
In the constructor of a derived class (a class that `extends` another class), `this` cannot be used before calling `super`:
|
||||
|
||||
```coffee
|
||||
class B extends A
|
||||
constructor: -> this # Throws a compiler error
|
||||
```
|
||||
This also means you cannot pass a reference to `this` as an argument to `super` in the constructor of a derived class:
|
||||
|
||||
```coffee
|
||||
class B extends A
|
||||
constructor: (@arg) ->
|
||||
super @arg # Throws a compiler error
|
||||
```
|
||||
This is a limitation of ES2015 classes. As a workaround, assign to `this` after the `super` call:

While it’s not recommended for serious use, CoffeeScripts may be included directly within the browser using `<script type="text/coffeescript">` tags. The source includes a compressed and minified version of the compiler ([Download current version here, 51k when gzipped](/v<%= majorVersion %>/browser-compiler/coffeescript.js)) as `docs/v<%= majorVersion %>/browser-compiler/coffeescript.js`. Include this file on a page with inline CoffeeScript tags, and it will compile and evaluate them in order.
|
||||
|
||||
In fact, the little bit of glue script that runs [Try CoffeeScript](#try), as well as the code examples and other interactive parts of this site, is implemented in just this way. View source and look at the bottom of the page to see the example. Including the script also gives you access to `CoffeeScript.compile()` so you can pop open your JavaScript console and try compiling some strings.
|
||||
|
||||
The usual caveats about CoffeeScript apply — your inline scripts will run within a closure wrapper, so if you want to expose global variables or functions, attach them to the `window` object.
