* Docs: named functions and function declarations * No more prototypal `extends`; update docs and example * More comprehensive documentation of the existential operator; closes #1631 * Better document operators, including `from` * No fat arrow class methods anymore * Destructuring shouldn’t say that default values are applied in case of undefined or null * Spinoff generator and async functions into their own sections; reorder things so that the sections on functions come just before classes, and destructuring goes next to the operators (which discuss assignment) * Rewrite “CoffeeScript 2” section, making it less practical and more explanatory; move practical info into “Usage” * Update “Variable Scoping and Lexical Safety” section to remove incorrect reference to Ruby (fixes #2360), add missing details about the safety wrapper, add note about `let`/`const`. * Updated browser compiler * Updated docs * Rewrite Literate CoffeeScript breaking changes * Split apart the “Breaking Changes” and “Unsupported Features” sections into separate sidebar items and files * Add example of `not in`, closes #3281 * Fix words in bold that should be in backticks * Consolidate some breaking changes sections * Add Node API documentation; closes #3551 * Move the chaining documentation out of the changelog into its own section

Generator Functions
CoffeeScript supports ES2015 generator functions through the yield keyword. There's no function*(){} nonsense — a generator in CoffeeScript is simply a function that yields.
codeFor('generators', 'ps.next().value')
yield* is called yield from, and yield return may be used if you need to force a generator that doesn’t yield.
You can iterate over a generator function using for…from.
codeFor('generator_iteration', 'getFibonacciNumbers(10)')
