title: create array in reverse order
body: <p>I've got buttons with a common class (<code>buttons</code>). How can I add their <code>ID</code>s in to an array in a reverse order?</p>
  
  <pre><code>var yourArray = [];
  $('.buttons').each(function() {
       yourArray.push( $(this).prop('id') );
  });
  </code></pre>
