title: Check if one array is contained in another array
body: <p>I have</p>
  
  <pre><code>['a', 'b', 'c']
  </code></pre>
  
  <p>I want to know if this array is contained in this array: </p>
  
  <pre><code>['a', 'b', 'c', 'd']
  </code></pre>
  
  <p>I know I can do 2 for loops and check item per item, but is there a oneliner for it? </p>
