Assemblyscript is unfortunately not that fast (yet?), same as javascript in most cases, also because it uses a garbage collector.
"in general I'm seeing that Javascript performance is underrated, and WASM performance is often overrated - sane Javascript, WASM and native code can all be in the same performance ballpark, but native code usually has the most "optimization potential""
And strong disagree. Javascript is indeed quite fast, but if you use a native compiled wasm libary in the right way (avoiding too many calls to wasm and back) - you will get a worlds difference in performance.
Well yeah, that because each call is basically an "optimization barrier" for the compiler (on both sides of the call), and of course the call itself also adds overhead, although that has been drastically reduced over the years.
