 Conceptually, [generators](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/function*) allow you to write a function that acts like an iterable sequence.  Generators support the standard ES6 [Iterator interface](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/The_Iterator_protocol), so they can be iterated over using ES6 standard `for of` or the iterator's `next()` API.
