body: <p>I have the following structure in the project im working on (uses immutable JS):</p>
  <blockquote>
  <pre><code>data :[{name: 'john', surname: 'smith', children: [{name: 'sam'}, {name: 'ben'}]},
         {name: 'jane', surname: 'jones', children: [{name: 'tim'}, {name: 'amy'}]}]
  </code></pre>

  <p>I need a new object in the following structure:</p>
  <blockquote>
  <pre><code>data :[{name: 'john', surname: 'smith', children: ['sam','ben']},
         {name: 'jane', surname: 'jones', children: ['tim','amy']}]
  </code></pre>
