title: Comma-delimited properties to actual properties with Underscore or Lo-Dash
body: <p>If I have something like</p>
  
  <pre><code>var obj = [{keywords: "a, b, c"}, {keywords: "d, e, f"}]
  </code></pre>
  
  <p>and do</p>
  
  <pre><code>var result = _.pluck(obj, 'keywords')
  </code></pre>
  
  <p>I get</p>
  
  <pre><code>result == ['a, b, c', 'd, e, f']
  </code></pre>
  
  <p>I'd like to have</p>
  
  <pre><code>result == ['a', 'b', 'c', 'd', 'e', 'f']
  </code></pre>
  
  <p>is there any simple, short way to accomplish that with underscore or lo-dash? Without iterating over result, doing a string split and putting that into a new array?</p>
