What makes Rust's enums so great?
variant and @practical-fp/union-types can get rid of that boilerplate as well. Disclaimer: I am the author of the latter.
-
Generic Object Type with similar parameters in TypeScript?
That's called a discriminating union type. I've made a small library to make discriminating unions easier to use. There also plenty of other excellent libraries like variant.

Help mapping JSON string to types
I've written a small library to get rid of most of the boilerplate required to use this pattern. It's however not the only library which does that. Also have a look at variant.

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.
