Is there any way to get code completion for imported JavaScript in NetBeans or other IDEs?

Question

I'm starting to learn java script by developing a webapp. I'm specifically working with google maps API. Coming from a Java/C++/C# desktop development background, I find it very frustrating to program using the imported code supplied by Google, without being able to "shop for options" using code completion. Is there any way to get this in Netbeans or other IDEs (I'm willing to learn a new IDE to go with learning a new language)?

Answer 1

Visual Studio has javascript autocomplete (they call it "IntelliSense"), but you come from a C# background, so I would have thought you would know that.

Edit: I don't know how advanced the intellisense has become with Visual Studio 2012, but in earlier versions you would often use a vsdoc.js file that includes all the information you would need. For instance, here's a file somebody made for Google Maps API 3: http://gmapvsdoc.codeplex.com/releases/view/41099
