That tsts project looks very interesting. I suppose there are various practical reasons for doing this. For me I'm just glad to see an easy way to run the newest TypeScript compiler (and I guess type checker?) in the browser. There's an unofficial Wasm build of tsgo/ts7, if I recall was about 12Mb. Another advantage of tsts I imagine is the ease of diving into the compiler internals as it's running (interpreted) instead of a binary distribution, another language (though I like Go), or having to recompile it on every change. Good luck with the project, I'll be keeping an eye on its progress with interest.
