title: find transposed matrix using lodash
body: <p>I have an array:</p>
  
  <blockquote>
    <p>[
       [1,2,3],
       [4,5,6]
    ]</p>
  </blockquote>
  
  <p>How can I turn it into</p>
  
  <blockquote>
    <p>[
       [1,4],
       [2,5],
       [3,6]
    ]</p>
  </blockquote>
  
  <p>I am sure it's something I can do easily with lodash but I have not found it in the docs.</p>
