I just used IDEA to write my first HTML game using Typescript and the CreateJS libraries. Just wanted to say it was a more pleasurable experience than I have *ever* had writing Javascipt, and even with the tools being new, it's working prettty much as advertised.
Thanks Jetbrains, IDEA rocks! Typescript support rocks even harder! Maybe the future of client-side coding isnt quite so bleak as I had assumed. :)
