I'm not sure it would be either. JS has a good JIT that Java code can significantly benefit from (much more than, say, C) -- WASM doesn't, so compiling to JS could actually be faster; JS also has a GC and WASM doesn't, which means that the image must contain a GC, making it larger, not smaller. Either way, it's speculation, but I don't think it's obvious that compiling Java bytecode to WASM is preferable to compiling it to JS, but maybe the TeaVM maintainers can share their experience.
