当然不是咖啡!

12.2 PureRenderMixin

当你的 props 和 state 都是 immutable 的时候…

      var PureRenderMixin = require('react-addons-pure-render-mixin');
React.createClass({
  mixins: [PureRenderMixin],
  render: function() {
    return <div className={this.props.className}>foo</div>;
  }
});

12.3 shouldComponentUpdate

可以通过这个方法对于 component 到底什么情况下应该重新 render 调优
