Javascript Debugger

I've been a user of MyEclipse for my Java development needs for quite some time now. It is a fully fledged J2EE development environment on a par with Rational or any of the other tools but it only costs $53 per year to run. What I didn't know is that it also includes a fully fledged Javascript Debugger which knocks anything else I've tried, including Firebug and the Web Developer Toolbar into a cocked hat.

If you're a Java or web developer you owe it to yourself to check MyEclipse out.
