title: Is there any last() in YUI NodeList?
body: <p>Let's say I try to select the last child of a list of nodes in YUI3:</p>
  
  <pre><code>var node = Y.one('#node');
  node.all('button').last();   // pseudo-code, not actually working!
  </code></pre>
  
  <p>Is there an equivalent to jquery's <code>last()</code> (and <code>first()</code>, respectively) in YUI3?</p>
  
  <p>I checked the <a href="https://yuilibrary.com/yui/docs/api/classes/NodeList.html" rel="nofollow">API docs</a> and did not find anything comparable.</p>
  
  <pre><code>node.one('button:last-child')
  </code></pre>
  
  <p>did'nt do the job either.</p>
