What is the dollar symbol used for in ASP.net?
<p>I know this might be a newbie question, but every-time i see code like this:</p>

<pre><code>var table = $("table[title='Refresh']");
</code></pre>

<p>And also code like this:</p>

<pre><code> $(function () {
        $("#datepicker").datepicker();
    });
</code></pre>

<p>i always sort of glaze over the <code>$</code> symbol .  It's a type of placeholder? or does it signify that its dynamic?</p>
