title: Removing objects from an array based on another array
body: <p>I have two arrays like this:</p>
  
  <pre><code>var arrayA = ["Mike", "James", "Stacey", "Steve"]
  var arrayB = ["Steve", "Gemma", "James", "Lucy"]
  </code></pre>
  
  <p>As you can see, <code>James</code> and <code>Steve</code> match and I want to be able to remove them from <code>arrayA</code>. How would I write this?</p>
