alt Hacker NewsI love how far Java has come. I still prefer TypeScript since I do a lot of frontend work and prefer to use the same language across the stack.
With the said, you can do exhaustive pattern matching in TypeScript! https://github.com/gvergnaud/ts-pattern

You don't need a library for this; the idiomatic approach is to lean on TypeScript's narrowing and native control flow (ifs and switches, or maybe IIFEs), along with (maybe) the never type to enforce exhaustiveness.

I guess the library is slightly nicer, arguably, but I don't think it's worth the external dependency and added complexity.
Isn't that overkill? You can check exhaustiveness with a trivial little helper:
