title: Transposing JSON
body: <p>I'd like to extract all the properties of a homogeneous JSON collection into it's own array.</p>
  
  <p>For example, given:</p>
  
  <pre><code>var dataPoints = [
      {
          "Year": 2005,
          "Value": 100 
      },
      {
          "Year": 2006,
          "Value": 97 
      },
      {
          "Year": 2007,
          "Value": 84 
      },
      {
          "Year": 2008,
          "Value": 102 
      },
      {
          "Year": 2009,
          "Value": 88 
      },
      {
          "Year": 2010,
          "Value": 117 
      },
      {
          "Year": 2011,
          "Value": 104 
      }
  ];
  </code></pre>
  
  <p>I'd like to extract an array of all Values from dataPoints that looks something like:</p>
  
  <pre><code>var values = [100, 97, 84, 102, 88, 117, 104];
  </code></pre>
  
  <p>Instead of iterating and constructing manually, is there a clean/efficient way to accomplish this kind of transposition?</p>
