What is most beneficial to use? $(this) vs. this
<p>When is it most beneficial to use <code>$(this)</code> and when should I use the plain old <code>this</code> (<code>$(this)[0]</code>)?</p>

<p>I have posted on <a href="http://stackoverflow.com">SO</a> before, where someone told me I shouldn't use <code>$(this)</code> so much in my function but rather <code>this</code>.</p>

<p>Why? Is <code>$(this)</code> rather memory intensive or something? Or does it sometimes contain more data than you are currently using in your function (too much overhead)?</p>
