In general, yes, although it's nice to have more than one javascript implementation. And one advantage of JSC is that it implements tail call optimization (per the ES6 spec).

I wrote my own language that targeted javascript. When I made my language self-hosting, I initially used `bun` (based on JSC), so I wouldn't have to implement a tail call transformation myself. It was expedient.

My goal was to run in a browser, so I did eventually add that transformation and found that my compiler was 40% faster running in node (based on v8).
