To be honest early TypeScript was quite bad with class dependence (functional style was an afterthought) and "namespaces" (That was still used in the mainline TS compiler until recently iirc, behaved like nested objects in JS, kind-of useful but totally missed the NodeJS file-based-module-separation) felt a lot like they wanted _Java_ or C#. Sometimes during the late 2.x series TypeScript really came into stride with ability to express more "dynamic" types, using a functional style and having arrays-behaving-like-tuples,etc and the 3.x and 4.x series has really made it polished. TL;DR; It's quite great now, but don't dismiss sceptical people because early versions of it kinda DID suck.
