Are there any free solutions that provide intellisense for JavaScript?

Are there any free editors that come with auto-complete / 开发者_运维问答intellisense for JavaScript programming?

As I try and do more complicated JavaScript programming I find my lack of ide/intellisense/compiler to really be a source of frustration.

Any JavaScript environment tips?

Visual Web Developer Express

You should try Aptana Studio. It is a complete JS IDE with massive functionality. But that depends on what you really need, may be PSPad would be enough.

Bespin is an interesting browser-based code editor.

NetBeans has decent JavaScript editing capabilities.

Komodo Edit

None of the tools available provide really decent "intellisense" for JS (the same level as Java), so don't get your hopes up.
