What program do you use for your JavaScript editing?

Do you like it? How much was it?

Actually, I'm looking for a very bare-bones program, but am interested in all of the available editors, nonetheless.

Ideally, I would use something smarter than Notepad but something that still had a fast start-up and editing time. For instance, Dreamweaver has so many other features it's really inefficient to use it to just edit JavaScript code.

Thanks in advance for any suggestions.
