ADTs in Typescript
When working in a TS codebase I'll lean on this variant library, which works pretty well as far as simple sum types go (v3 is great but not stable yet).

disc-union - (yet another) library for working with discriminated union types
About half-way through writing this library I discovered that Variant existed... and does a great job at doing the exact same things (and more). I might not have started if I knew about that, but I'm glad I did because it has been a great learning experience!

ts-pattern: pattern matching library for TypeScript, with smart type inference
Oddly enough, this feature alone has been a a big draw to Rust, Haskell and functional programming in general for me... so it's nice that there's libs filling the gap for TypeScript. Here's another one I haven't gotten around to trying yet either.

Tool to normalize types (specifically intersections)?
I had to solve this for a project of mine.

You Don't Need React
ts-pattern has been a decent band-aid for the lack of native pattern matching, but obviously has downsides that could be avoided if it was built into the language.

TypeScript Is Surprisingly OK for Compilers
With how powerful the type system is you can implement pattern matching via a library pretty convincingly, https://github.com/gvergnaud/ts-pattern is definitely the go-to. That being said pattern matching is hardly a requirement for being ok for implementing compilers.

[AskJS] C# in every Node.js job posting?
There's a proposal to add something like that to JavaScript but it's been stuck in limbo since 2017 although there are libraries like ts-pattern which implement it already.
