title: React showing 0 instead of nothing with short-circuit (&&) conditional component
body: <p>I have the following simple short-circuit statement that should show either a component or nothing:</p>
  
  <p><code>{profileTypesLoading &amp;&amp; &lt;GeneralLoader /&gt;}</code></p>
  
  <p>If the statement is false, it renders a <code>0</code> instead of nothing.</p>
  
  <p>I have done a <code>console.log(profileTypesLoading)</code> just to see quickly what the status of the <code>profileTypesLoading</code> property is and it's either 1 or 0 as expected.  0 should be false... causing nothing to render.  Right?</p>
  
  <p>Any idea why this would happen?</p>
