How do you optimise your Javascript?

Question

Well... simple question, right? But with no so simple answers. In firefox i use firebug console (profile) but... what to do in other browsers? Like Internet Explorer / Opera / Safari (on windows)

Answer 1

This particular problem solves itself over time. ;-)

Version 8 of the Internet Explorer (currently in beta 2) ships with a built-in JavaScript profiler. The next Safari version will probably also include one since its rendering engine, WebKit, now has one as part of its Web Inspector.
