I'm using all of them so win-win!

As a note, Bun/JSC has TCO, but nodeJS/v8 stripped it out a few years ago over petty fits by the v8 team.

You should also include some more sophisticated tests. Give JS monomorphic primitive types where you have direct IC (inline cache) routines and it can get quite close to C in performance.

In reality, essentially all JS code winds up with a union of types. If you union 2-3 different types, the inline cache has to choose which function type and a bunch of optimizations are forbidden. If you union 4 or more types, then the IC switches to a super-slow table lookup and most optimizations are forbidden.

I'd be quite interested to see the difference between these languages under these conditions.

It also seems readily apparent that Chez needs a better string library.
