title: Accessing properties of an array of objects
body: <p>pretty basic question I think, but I couldn't find info on that.</p>
  
  <p>Through d3 I parse a csv and each object look like this</p>
  
  <pre><code>name: "whatever"
  number: "52"
  </code></pre>
  
  <p>How can I access the array of all the properties "number" as an array without creating a new array and pushing each element?</p>
