Go compiles to WASM but the stock compiler is pretty bad for this and your binaries are like 2MB+ in size.

TinyGo is an LLVM based compiler that targets microcontrollers but also has a WASM target and that creates considerably smaller binaries, but it doesn't fully support all of the Go standard library.

TinyGo is great, I used to to program microcontrollers and there wasn’t anything I really missed, though admittedly it was a very small program.
