title: Filter javascript multidimensional array for values that exist at every index
body: <p>Let's say that I have the following multidimensional array :</p>
  <pre class="lang-js prettyprint-override"><code>const arrayOfValues = [
    ['a', 'b', 'c'],
    ['a', 'c'],
    ['c']
  ];
  </code></pre>
  <p>I would like to create a new array containing only the values that are present at every index of my original multidimensional array. So I would end up with the following array in this case :</p>
  <pre class="lang-js prettyprint-override"><code>['c']
  </code></pre>
  <p>I'm having trouble finding a way to do so as I am not too familiar with javascript. I'm guessing I have to apply some sort of filtering (probably map over the array and apply a specific condition) but I'm not sure how to go about it.</p>
