The fact that you can not write a fast compiler for typescript using typescript and have to use go or rust for that does not make typescript bad per se.
it just marks well its scope of applicability. Business logic, routing rules, small pieces of messages handling glue code on edge devices or cloud functions, and other places where you mostly connect with glue code some other libraries of high-optimized code.
Well, from code based config to shell scripts, from website backends to in-game scripting. it is not that bad if a language can do all that, even if you can not write its own compiler to be fast on it.
BTW there are few interesting projects allowing to compile typescript to native executables based on rust. They have 95% coverage or so of Typescript compatibility with Nodejs as Perry.
I even think to use Perry for next my pet project (local-first blogigng tool).
