So just started to get stuck into my new book on TypeScript. My immediate feeling is TypeScript is amazing and makes JavaScript a zillion times better. What's others opinions?

Kotlin

This kotlin thing is getting ridiculous

Yes, much better and when building bigger web applications is almost must to have. At the same time you get to use the sweet ES6 syntax.

I'm not that extatique about it.
Sure static typing helps in building some kind of passive documentation to your code and it'll throw a few useful errors here and there.
But! The overhead to make it work is so high compared to babel and some proper jsdoc.

I'd honestly like some feedback as well.
