I guess I have to defend this one. I personally think Typescript is the better language compared to typed Python or Ruby (two comparable languages based on how they are all used). Modern Javascript actually have a lot of nice language features, the only issue is the lack of types. Typescript doesn't entirely solve the problem but it's a decent attempt at it. A good typescript repo is decently readable, testable and performant enough for most use cases.

Typescript is wasted on JS. Currently getting a JS certification while porting an action script 3 project to JS, ActionScript 3 was the better language.
