Does the browser "cache" javascript code?
<p>I was fine tuning a page that is heavy on jquery and stumbled across this website:</p>

<p><a href="http://www.componenthouse.com/extra/jquery-analysis.html" rel="nofollow">http://www.componenthouse.com/extra/jquery-analysis.html</a></p>

<p>When I click on the "Run Test" button the first time, the numbers are way higher than subsequent clicks. Is this because JS is cached by the browser? Can someone explain how this works internally? Can a user choose to not cache the JS?</p>
