* Build both a legacy and modern browser compiler
* Dynamic import example and documentation
* Update the docs to use the modern browser compiler if the browser supports it
* Update policy regarding Stage 3 features
* This never made sense, and assigning a string to index 0 *of a string* throws in Module mode (and silently does nothing in Script mode) so remove this unneeded code that throws when compiling `fn for i from from iterable` in Module mode
* Have browser-based tests use the ES module version if supported
* Simplify building logic
* Update output
* For the ES module version of the browser compiler, don't automatically attach the runScripts event handler
* Consistent comments
* Fix comment
* Un-prefer global (#4543)
* 1.12.6 changelog; update NPM module in documentation to be `coffeescript` instead of `coffee-script`; update installation to add note about global vs local `coffee` command
* Update packages
* Updated output
* Simplify changelog
* The generated JavaScript for the examples in the docs ends up within index.html, so we don’t need the intermediate generated .js files committed in the repo; also, even while .gitignored they should be under `docs`, with the rest of the generated files, not under `documentation`, where the source files are.
* Add “Existential Operator” to the table of contents. Closes#4361
* Updated output due to newer version of highlight.js
* Generated the JavaScript for the docs examples should be synchronous, so that index.html isn’t generated before the JavaScript is
* In “Try CoffeeScript,” if you press the tab key it should type a tab character. Closes#3342.
* Rename doc example folders from `js` and `coffee` to just `examples`
* Add missing `yield` to the list of keywords to highlight until highlight.js catches up; update the class used to match highlight.js’ `keyword`
* `cake doc:site` should watch the example files too, not just index.html.js
* Remove examples folder, including underscore.coffee; remove link to annotated underscore.coffee
