end() function
<p>The <code>end()</code> function in jQuery reverts the element set back to what it was before the last destructive change, so I can see how it's supposed to be used, but I've seen some code examples, eg: <a href="http://alistapart.com/articles/prettyaccessibleforms" rel="nofollow">on alistapart</a> <em>(which were probably from older versions of jQuery - the article is from 2006)</em> which finished every statement off with <code>.end()</code>. eg:</p>

<pre><code>$( 'form.cmxform' ).hide().end();
</code></pre>

<ul>
<li>Does this have any effect?</li>
<li>Is it something I should also be doing?</li>
<li>What does the above code even return?</li>
</ul>
