ES6 generators in depth

This blog post is outdated. Please read chapter “Generators” in “Exploring ES6”.


This blog post is part of a series on iteration in ES6:

  1. Iterables and iterators in ECMAScript 6
  2. ES6 generators in depth

Generators, a new feature of ECMAScript 6 [4], are functions that can be paused and resumed. This helps with many applications: iterators, asynchronous programming, etc. This blog post explains how generators work and gives an overview of their applications.

The following GitHub repository contains the example code: generator-examples

Using the ES6 transpiler Babel on Node.js

This blog post is outdated (it covers Babel 5). Please read Sect. “Node.js setup: Dynamically transpiled ES6 via Babel” in “Setting up ES6”.


This blog post explains how to use the ES6 transpiler Babel with Node.js. You can download the code shown in this post on GitHub. For further information on ECMAScript 6, consult the ebook “Exploring ES6”.

Warning: The approach explained in this post is convenient for experiments and development. But it uses on-the-fly transpilation, which may be too slow for your production code. Then you can transpile as a build step (as explained in the Babel documentation).

This blog post looks at destructuring from a different angle: as a recursive matching algorithm. At the end, I’ll use this new knowledge to explain one especially tricky case of destructuring.

No promises: asynchronous JavaScript with only generators

Two ECMAScript 6 [1] features enable an intriguing new style of asynchronous JavaScript code: promises [2] and generators [3]. This blog post explains this new style and presents a way of using it without promises.
