Get ECMAScript 5 Intellisense in Visual Studio

Question

Are there any known solutions to supporting ECMA 5 features in Visual Studio's Intellisense?

For example, it would be nice to have Object.create() and Object.defineProperty() as well as all of the new methods and functions on the native types.

Answer 1

I tested the developer preview of Visual Studio 11, and much of ECMAScript 5 is supported by Intellisense. I don't see solutions for support in VS 2010, so I guess the answer is: Wait for VS 11.
