See also webghc which has an alternative strategy to writing a new RTS and code generator. They are cross compiling to wasm via llvm. https://webghc.github.io/2019/01/18/state-of-webghc-january-...

I'm curious how they solve garbage-collection, since last time I checked WebAssembly doesn't yet support that?

Presumably it’s implemented “natively”. Just like it would be on a native pl.

I don’t think it has gc yet ..

So far they use the "don't" approach to garbage collection. It would have to be implemented.like the rest of the rts.

I guess parts of the c code could be transpiled but something low-level like the gc relies on details like register pinning.

Surprised to see that no one has mentioned GHCJS " rel="nofollow">https://github.com/ghcjs/ghcjs> still.

I have used it[0] a year ago and despite my shallow understanding of Haskell, I have managed to port my CLI app to Haskell fairly easily!
