Rust: Enable WebAssembly backend by default. What about Go?

Today I saw that with a latest change in Rust you can compile to WebAssembly without additional tools. So I wanted to ask if there's any effort from the Go team or the community for something similar in Go.

It's being worked on. https://github.com/golang/go/issues/18892

TUSF:

Neat. There was even an update several hours after you posted this.


I am very happy about the progress in a month and a half, and only in my spare time. I think there is a good chance that we could get this into Go 1.11. Expect my next update in January, since I'll be on vacation and then there are the holidays.

Can't wait.

Someone has started doing this. https://github.com/golang/go/issues/18892#issuecomment-341714912. But it hasn't reached to any stage yet.

IIRC, LLVM can compile to WASM, and there is Gollvm. There is also GopherJS. But yeah, I'd prefer an actual compiler to WASM.

feketegy:

Go to WASM? That would open up a whole lot of possibilities

birkbork:

Except for more performance, what possibilities are you thinking of that we cannot already get with https://github.com/gopherjs/gopherjs

monkey-go-code:

I really can’t think of anything more important than performance.

username checks out

feketegy:

Are you comparing JavaScript to Assembly? LOL :)

Assembly is as close as you can get performance wise, unless you're a savant and want to write machine code

birkbork:

I am not comparing, no. Just pointing out that there is a go->browser path today.

Still wondering about the possibilities.

As a fan of Go, this made me chuckle. Not enough to upvote, but thanks anyway.
