Just In Time compilation in WebAssembly (2022)

Part of a larger saga of running spidermonkey inside wasm, finding that it is too slow even though it boots fast, and so adding JIT. I found it while poking around different people’s toy scheme inplementations, and this one stood out because it looks to me like it is an entire jitting interpreter, written by hand pre llm, for the sole purpose of adding an interactive demo to a non lisp related blog post.
