Safer Type Checking At Both Runtime and Compile Time
Otherwise, go for a pattern matching implementation like ts-pattern (which has exhaustiveness checking and has a builder pattern API) or ex-patterns (which im not sure if it has exhaustiveness checking, but it's a little more capable and is inspired by pattern matching in elixir, and has an argument order based API)

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.
