Javascript code editor with intelligence

Question

Is there any code editor or even IDE, where you can get some compassion in the form of "method" auto-complete suggestions and "jump to definition", for your javascript code that uses a library like d3.js?

Answer 1

I have found that WebStorm does all that. Need to follow here to set it up to know your external library (e.g. d3.js in my case) so that it can be smart about it. Download the unminified/debug version of your library first so you can supply it in that dialog. Installing WebStorm was quick and a no-brainer.

If you know of other tools that have these capabilities, please post your answer as well...

WebStorm currently doesn't cost all that much and currently comes with a 30 days trial.
