Confused about when saving a variable using the $() function
<p>In jQuery, if I do this:</p>

<pre><code>var a = $("#someid");
</code></pre>

<p>Now when I need to further reference using jQuery, what should I be doing?</p>

<pre><code>$(a).attr("id");
</code></pre>

<p>or</p>

<pre><code>a.attr("id");
</code></pre>

<p>I'm testing things out and I'm getting confused, just want the official word so I can rule this out.</p>
