Uses of .sub() in real life
<p>I stumbled upon the <code>.sub</code> function from browsing the jQuery source. There is a <a href="http://api.jquery.com/jQuery.sub/" rel="nofollow">documentation page</a> but it doesn't show any convincing 'real-life' applications.</p>

<p>Do people actually use <code>.sub()</code>? If so, for what?</p>
