Not just javascript, but any WASM runtime.

With spasm I was auto-generating all glue code based off of 
WebIDL files. The post build step was annoying but it worked 
pretty well.

I even had a prototype that would do it for any typescript 
library.

Of course using WASM ref types is way more ergonomic.

One thing to note about WASMGC, it is MVP and missing a lot of 
things like support for interior pointers etc. There are 
workarounds but it's not so simple.
