I don't know about other JS frameworks, but I've seen many people say they love angularJS, and I believe that's true, because that's exactly how I feel about angularjs ;)

I'm from a Windows dev background and all other exiting code editors/IDE I tried doesn't satisfy me so I'm building a new one.

And a handy tool is only a half for me to happily switch to web front end dev, and another half is a good framework, and I think angularjs can be that framework.
