Best Open Source Javascript Editor

I found Komodo Editor by a youtube video reference and it was a GREAT edition to my Javascript Editors :P Too many editors. Unlike Visual Web Developer you can

•  Fold the code, not only function blocks but also every curly brace block which is extremely cool
• Click beside the starting bracket it will select the ending one, bravo.
• The Dark theme is cool, I have started liking working with black background.
• You can open not only files but also projects.
• You associate file extensions with appropriate programming language. By default aspx is not associated, I bound with HTML view. I could have used XML too. The code folding works on that file too. Even that is server side code. For that go to Edit > Preferences > File Associations.
• You can customize the colorization experience by Edit > Preferences > Fonts and colors. 
• On the top toolbox you can "Show/Hide left pane" etc so you can view project browser on demand.
• The vertical lines to show matching braces is a cool feature.
• Guess what ! GO TO DEFINITION in javascript? ;) 
• Code intellisense is also there. Liked it. It remembers variable names, function names and shows common objects such as window and document and their functions like alert() and parseInt() etc. 

I din't expect this much of features from a non-MS editor specially this level of javascript support which is leaving Microsoft Visual Web Developer behind many years.
