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)')
