Wasm itself is at the level of assembly, not the level of JavaScript. If you want to compile a GC'd language to wasm, you have to bring your own garbage collector and compile it to wasm as well. That's not a showstopper from wasm's perspective, and several languages have done just that, but porting a GC to a new compilation target can be a bit of work.
