title: One line Arrow function, return multiple
body: <p>I am using ReactJS and I am having trouble getting an arrow function to return multiple functions.</p>
  
  <p>I have a one line arrow function on an onLoad event:</p>
  
  <pre><code>&lt;iframe onLoad={() =&gt; (this.handleFrame &amp;&amp; this.setState({loadingComplete: true}))}&gt;&lt;/iframe&gt;
  </code></pre>
  
  <p>The above code does not work. How I can return both <code>this.handleFrame</code> &amp; <code>this.setState({loadingComplete: true})</code> on one line of code?</p>
