title: How to 'pop' or 'shift' from jQuery set
body: <p>In Javascript, arrays should have methods <em>pop</em> and <em>shift</em>.</p>
  
  <p>However, JQuery objects seem to be missing these methods:</p>
  
  <pre><code>$('div').shift(); // Error, shift is undefined
  $('div').pop(); // Error, pop is undefined
  $('div').splice(); // Splice is OK actually
  </code></pre>
  
  <p>I wonder why these functions are missing - after all, the jquery object is just an array.</p>
  
  <p>What's the easiest way of performing pop and shift functions on jquery objects?</p>
