Testable JavaScript Resources

Testing JavaScript isn't just a thing you can read about in children's fairy tales.

This is just a scratch pad of everything I find. As the really good resources start to float to the top, I'll transition them to a more permanent GitHub repo.

General

• Test-Driven JavaScript Development [book]
• JavaScript Testing Recipes [book]

"Parens and Performance" – counterpost

Kyle Simpson (@getify) wrote a very thoughtful post decrying optimize-js, which is a tool I wrote that exploits known optimizations in JavaScript engines to make JS bundles parse faster (especially minified bundles, due to what could be reasonably described as a bug in Uglify).

Kyle lays out a good case, but I tend to disagree with nearly all his points. So here's my rebuttal.

Open source is an important part of the react ecosystem. Most of the time you'll use components written by others, but you may wish to create components other people can use. For this guide, you'll need to have node.js and git installed.

Setup

First you'll need to create a project directory, and open a terminal in that directory. React components are published as npm packages, so we need a package.json file. To create one, run npm init and follow the prompts.
