I never had a time to take a look at type script.
What is the benefit of adding static typing to an inherently dynamically typed language?
As I understand, they don't get any performance improvement from that, as the browser still runs it in JS vm?

If anything, I think most typed languages don't go far enough in making assumptions about their data explicit, and there is far too much primitive obsession. In an ideal world, I would not have to ever refer to documentation to understand what subset of inputs from the type that is declared on a function parameter are actually valid - a function that only handles integers from 0 to 100 would raise a compiler error if I tried to pass it 200, and whole classes of runtime errors would become impossible, and vast swathes of trivial unit testing harnesses would be irrelevant.
