title: ReactJS conditional rendering IF/OR
body: <p>Is it possible to render an element based on a IF/OR statement?</p>
  
  <p>I tried something like:</p>
  
  <pre><code>{!this.props.this || this.props.that &amp;&amp; &lt;button&gt;Some button&lt;/button&gt;}
  </code></pre>
  
  <p>but that doesn't work.</p>
