title: LoDash: Get an array of values from an array of object properties
body: <p>I'm sure it's somewhere inside the LoDash docs, but I can't seem to find the right combination.</p>
  <pre><code>var users = [{
        id: 12,
        name: 'Adam'
     },{
        id: 14,
        name: 'Bob'
     },{
        id: 16,
        name: 'Charlie'
     },{
        id: 18,
        name: 'David'
     }
  ]
  
  // how do I get [12, 14, 16, 18]
  var userIds = _.map(users, _.pick('id'));
  </code></pre>
