title: Lodash: how to create a array with new object structure
body: <p>Let's say I have an array: </p>
  
  <pre><code>var users = [
    { user: 'barney', age: 36, active: true },
    { user: 'fred',  age: 40, active: false },
    { user: 'travis', age: 37, active: true}
  ];
  </code></pre>
  
  <p>I want to create a new array:</p>
  
  <pre><code>var users = [
    {person: {item : { user: 'barney', age: 36, active: true }}},
    {person: {item : { user: 'fred',  age: 40, active: false }}},
    {person: {item : { user: 'travis', age: 37, active: true}}}
  ];
  </code></pre>
  
  <p>Obviously, workaround is using for loop to create new array, but I'm using lodash for manipulating my arrays in my project. </p>
  
  <p>Just wonder is there any lodash solution for this.</p>
