Add handler multiple times in jquery
<p>How does jquery handle event assignment when it comes to assigning the same handler multiple times?  Let's say I have </p>

<pre><code>&lt;div class="draggable"&gt;Some Text&lt;/div&gt;
</code></pre>

<p>Are there any side effects (performance or otherwise) from calling the following multiple times?</p>

<pre><code>$('.draggable').draggable();
</code></pre>
