How can I inject a common code in components in React
<p>For multiple React component , I want to inject a common code to the life cycle of React.<br>
Is there something good way?</p>

<pre><code>var ComponentA = React.createClass({
    componentWillMount: function () {

    },
    componentDidUpdate: function(){
      //inject common code
    },...

var ComponentB = React.createClass({
    componentWillMount: function () {

    },
    componentDidUpdate: function(){
      //inject common code
    },...
</code></pre>
