title: A jQuery question about variables and selectors
body: <p>Lately, I have been doing this in an effort to speed up performance (and sometimes it helps with maintainability)</p>
  
  <pre><code>var objectToReference = $('div .complicated #selector ul:last');
  </code></pre>
  
  <p>So what does <code>objectToReference</code> really hold? Sometimes things have bitten me, so I've gone back to using the full selector and it has worked.</p>
  
  <p>So does the variable hold a reference, a pointer, etc (I'm not sure the exact definition of those terms)</p>
  
  <p>Thanks</p>
