React Notes

JSX is a JavaScript syntax extension that looks similar to XML. You can use a simple JSX syntactic transform with React.

You don't have to use JSX with React. You can just use plain JS. However, we recommend using JSX because it is a concise and familiar syntax for defining tree structures with attributes.

React can either render HTML tags (strings) or React components (classes).

React's JSX uses the upper vs. lower case convention to distinguish between local component classes and HTML tags.

Mofo Testing Notes

General approach for functional testing:

Do programmatic user interactions via headless browser and analyze the resulting DOM mutations.

PhantomJS

• Gotcha: Phantom 2 downloaded from official site doesn't work on Yosemite. Get a working binary here.
• mocha-phantomjs looks promising but isn't on 2 yet.

gvn

window.Component = {
	init: function () {
		var self = this;

		self.events.parent = self;
		self.callbacks = {};
	},
	events: {
		actionHappened: function (event) {
			var self = this.parent;
