stop processing in javascript

Question

Is there a way to exit a javascript script without tracking back through all called functions with return. Sort of like a gasp GOTO. Or maybe setting an infinite timer that does not take up too much CPU time. I want to use this to stop processing and warn user on unexpected exception/error cases.

The only way to make JavaScript in a browser stop running is to use an "alert()" or "confirm()" dialog. — Pointy

Pointy: after alert() javascript process still continues so how you stop that process ?! — Muflix

In unexpected or exceptional cases, throw an exception. You still should have a root try/catch block so that it doesn't affect anything else.
