title: getElementsByClassName vs. jquery
body: <p>If my original function was:</p>
  
  <pre><code>document.getElementsByClassName('blah')[9].innerHTML = 'blah';
  </code></pre>
  
  <p>...how would I change that so I get that same item in jquery? I have this, but when I put '[9]' at the end it doesnt work:</p>
  
  <pre><code>$(data).find('.blah')[9].html();
  </code></pre>
  
  <p>It I leave the [9] out, it only gets the first item whose class name is 'blah', and I want it to get the 10th item.</p>
