Reading the responses here, why are people so mad about types? Maybe I'm biased coming from a background of statically typed languages and mathematics. I'd rather have a good typing system that makes me think about data than just hoping I've thought about a problem right.
I have valid criticisms of statically typed languages, based around code patterns that are both expressive and efficient that are either difficult or impossible to implement in a statically typed language without "an ad hoc, informally-specified, bug-ridden, slow implementation of half of Common Lisp."
Typescript, however, is different. Its type annotation functionality is not the same as a static type system, which means I get to keep all those things I like about dynamically typed languages while still having compile-time validation.
Flip-side, however, is the complete lack of runtime validation in typescript, and the fact that junior developers trip on that a lot. I would call that a real advantage of javascript (if not enough to stop me from using Typescript). Having no check at all is better than being convinced typescript is protecting you when it's not.
