Nashorn is anywhere to faster on primitive heavy computation to 50% slower post JIT. Graal is supposed to be even faster. > Web Assembly has unsigned integer arithmetic This is your idea of a major difference that affects implementation so much that is separate VM needs to be written? Many Java programs already do essentially manual memory management already too. Those aren't the big differences. Things like safe-memory access are bigger issues. And once wasm gets gc, it will even be closer to Java and JS. I hope Graal outperforms everything else, so we can stop pretending like WASM is something different than what Java has been trying to do.
