When an external JavaScript file is referenced,

<script type="text/javascript" src="js/jquery-1.4.4.min.js"></script>

is the JavaScript source (lines of code before interpretation) available from the DOM or window context in the current HTML page? I mean by using only standard JavaScript without any installed components or tools.

I know tools like Firebug trace into external source but it's installed on the platform and likely has special ability outside the context of the browser sandbox.
