Declaring a var instead of using .find multiple times?
<p>I have been reading on best practices and I have come across this one:</p>

<p>Dont do this:</p>

<p><code>$("#element .child").hide()</code></p>

<p>Do this:</p>

<p><code>$("#element").find('.child').hide()</code></p>

<p>Now my question is what if i want to hide/show the <code>.child</code> element multiple times, should I declare it like this:</p>

<pre><code>var spinner = $("#element").find('.child');
spinner.hide();
</code></pre>

<p>or do I just keep calling <code>$("#element").find('.child').hide()</code></p>
