difference between $ and $() in jQuery
<p>Could someone take the effort to explain me the difference between <code>$</code> and <code>$()</code> in jquery?</p>

<p>I know <code>$()</code> is shorthand form of <code>$jQuery()</code> which takes any DOM element and turns it into a jQuery object. </p>

<p>But what I am not sure of is what is <code>$</code> and how different is it from <code>$()</code>. Kindly enlighten me.</p>

<p>Thanks heaps,
Chaitanya </p>
