Alternative to jQuery's .last
<p>I need to use the 1.3.2 library which unfortunately does not support the last functionality. This causes my function to fail:       </p>

<pre><code>$op.last().next().after($op);
</code></pre>

<blockquote>
  <p>"$op.last is not a function"</p>
</blockquote>

<p><strong>Demo:</strong></p>

<p>I have been unsuccessful at rewriting this functionality in pure js, any suggestions? Note, I will also need the .first(), but I'm assuming I will be able to extrapolate that from the .last alternate code. Many thanks-</p>
