It's generally trivial for conventional class-based type systems like those in Java and C#, but TypeScript is a different beast entirely. On the surface it seems similar but it's so much deeper than the others.

I don't like it. I know it is the way it is because it's supposed to support all the cursed weird stuff you can do in JS, but to me as a fullstack developer who's never really taken the time to deep dive and learn TS properly it often feels more like an obstacle. For my own code it's fine, but when I have to work with third party libraries it can be really confusing. It's definitely a skill issue though.

I agree. Typescript is different for another reason too. They ignore edge cases many times, and because of that you can do really-really nice things with it (when it’s not broken). I wondered a lot of times why Java doesn’t include a few things which would be appropriate even in that world, and the answer is almost always because Java cares about edge cases. There are notes about those in Typescript’s doc or issues.
