I'm a big fan of dotTrace for my web application and I wanted to find a solid javascript profiler that functions about the same way. I've looked around and can't seem to find a JavaScript profiler like that.

Anyone know of a Javascript profiler like dotTrace?

Firebug has a decent profiler built in, plus lots of other useful stuff. Please be more specific if there are particular features you're after.

A Javascript profiler is included with IE8: http://blogs.msdn.com/ie/archive/2008/09/11/introducing-the-ie8-developer-tools-jscript-profiler.aspx . It has reports and output that look somewhat like dotTrace.

There's a plugin for Firebug called YSlow that I would recommend if you're looking for performance improvements.

Also, the Venkman debugger offers profiling. Here's the latest version.

There is always the Firefox plug-in called Firebug.
