Get javascript object property via key name in variable
<p>Say I have something that looks like this in javascripts:</p>

<pre><code>var obj = {
  subObj : {}
};
var type = 'subObj';
</code></pre>

<p>How can I get <code>obj's</code> <code>subObj</code> w/ <code>type</code>? For instance I would like to do something like:</p>

<pre><code>obj.(type);
</code></pre>
