People into this sort of stuff might be interested to know that s7 Scheme also runs really well in WASM. It's 100% ansi C and uses its own GC, so getting it compiled and running in WASM is very simple. I use it in both my audio project (Scheme for Max, an s7 interpreter in Max/MSP) and in a browser based set of music practice tools I am working on as a solopreneur. It's fantastic to be able to write the music theory engine in Scheme instead of JS.

An example page (not mine) of it running in the browser is here: https://actondev.github.io/s7-playground/

I really hope the racket effort gains traction too! Excited to see this. In comparison, s7 is much more minimal. Though this also means the FFI is dead simple too, so extending it and bridging to js functions is much easier, and everything in s7 is available now in WASM - CL macros, keywords, hashtables, first class environments, continuations, etc
