What does x(); refer to?
<pre><code>var y = new w();
var x = y.z;

y.z= function() {
      doOneThing();
      x();
   }
</code></pre>

<p><em>where <code>w</code> does not contain a <code>z</code> object but contains other objects (e.g, <code>a</code>, <code>b</code>, <code>c</code>)</em></p>

<p>What is <code>x();</code> possibly referring too? (Again, this is JavaScript)<br />
Is the function calling itself?</p>
