Try webstorm , but dont expect the C#/Winforms level of integration. no GUI builder , no smart intellisence , etc ... it is because of the nature of javascript.
Yes, it's pretty great, although it's not fast enough in my experience, WebStorm will be my choice if I don't make my own. But the project (called LIVEditor) I'm working on is different - imagine a smart code editor is seamlessly integrated into Chrome browser (with the html inspector enabled) :)
