jQuery children returns a boolean?
<p>I've come across this line and I can guess what it's doing but shouldn't there be a <code>length &gt; 0</code> on the children or will it always return/can be used as a boolean?</p>

<p>Or does jQuery's children return a boolean, or is this person relying on the existence of the returned children?</p>

<pre><code>append(($(this).children()) ? '&lt;div class="vAlignWrapper" style="overflow: hidden;"&gt;' + $(this).html() + '&lt;/div&gt;' : '&amp;nbsp;').
</code></pre>

<p>I'm trying to debug a large JS file and I'm trying to make sure each line does what its supposed to do.</p>
