That's a pretty strange statement. TypeScript support does not mean you have to use TypeScript. It's purely additive by design.

By hacky I mean "define some global variables and the compiler will do some checks to make sure you don't do anything untoward". You can see my other post in this thread for examples where this model falls apart.
