title: react function not render anything
body: <p>I have problem rendering my ajax data in react.js.
  In my render function I have</p>
  
  <pre><code>{!isLoading &amp;&amp;
      this.renderList(items)
  }
  </code></pre>
  
  <p>My renderList function as below</p>
  
  <pre><code>renderList(items) {
    ...    
    ...
  
    const renderLi = (statusObj) =&gt; {
  
      return ( &lt;h1&gt; something &lt;/h1&gt; ) 
  
    }
  
    statusList.map(renderLi);
  }
  </code></pre>
  
  <p>I suspect it's async problem, I console items in my renderList it did got the array of object through param passing, I'm lost.</p>
