Saw this post on HN about optimizing AngularJS (http://blog.scalyr.com/2013/10/31/angularjs-1200ms-to-35ms/) and I wondered how React would fare. Turns out it can be pretty fast. I did have to use a similar trick of breaking up the line only when the mouse is over it, but no messing with custom directives needed. You can try it yourself by dropp…
/**
* @jsx React.DOM
*/
var text1 = document.getElementById('text1').textContent;
var text2 = document.getElementById('text2').textContent;
var LinksDemo = React.createClass({
getInitialState: function() {
return {text: text1};
