title: Remove the last item from an array (and not return item)
body: <p>My current array: <code>abc = ['a', 'b', 'c', 'd'];</code></p>
  
  <p>I understand <code>.pop()</code> remove and returns the last item of an array, thus: <code>abc.pop(); = 'd'</code></p>
  
  <p>However, I want to <strong>remove the last item</strong>, and return the array. So it would return:</p>
  
  <p><code>['a', 'b', 'c'];</code></p>
  
  <p>Is there a JavaScript function for this?</p>
