<p>What is purpose of using <code>void</code> here ? if just remove <code>void()</code>, it should also work, right?</p>

<pre><code>var b=document.body;

if(b&amp;&amp;!document.xmlVersion) {
   void(z=document.createElement('script'));
   void(z.src='http://www.google.ca/reader/ui/subscribe-bookmarklet.js');
   void(b.appendChild(z));
}
else {
  location='http://www.google.com/reader/view/feed/'+encodeURIComponent(location.href);
}
</code></pre>
