title: removes elements from array javascript (contrary intersection)
body: <p>Yesterday nigth I maked this question <a href="https://stackoverflow.com/questions/29711165/delete-elements-from-array-javascript">Delete elements from array javascript</a>
  But I mistook, my explanation and my example were about an intersection between two arrays.<br>
  What I wanted to ask is about how remove elements on array that doesn´t exist on other array.<br>
  <strong>Example</strong>:  </p>
  
  <pre><code>Array A=&gt; [a, b, c, d]  
  Array B=&gt; [b, d, e]  
  Array C= removeElementsNotIn(A, B);  
  Array C (after function)-&gt; [a,c]
  </code></pre>
  
  <p>Thank you very much.</p>
