Have you actually tried TypeScript? It feels just like writing JavaScript, but with a thin layer of type annotations that bring you the familiar advantages of static typing.

It seems to me that JavaScript haters would be better off moving to a completely different language, like ClojureScript. TypeScript rather feels like it's made for people who enjoy JavaScript but wish it provided the peace of mind of static typing.

I tried TypeScript for the first time a few months ago and it was a breeze. I felt "fluent" almost instantly and only had to look up the docs a few times. With ES6+ picking up steam, TypeScript-specific features are being replaced by their ES6+ equivalent, so TypeScript is going to feel even more natural going forward.
