Is there any point of using "return !0" in javascript?
<p>If you go to a google result page, and run <code>rwt.toString()</code>, you'll see that the return call for this function is:</p>

<pre><code>return !0;
</code></pre>

<p>I can't think of any reason why this wouldn't always be <code>true</code>. Is this just a shorthand for <code>true</code>, or is there more going on here?</p>
