Well, there are a couple of reasons. First, if you've never used JavaScript and don't fully understand how it works you can use a more familiar language like Go. Second, you can use the entire std library including Go's very strong http support. Third, you can use go routines and channels for easy multiprocessor computation. Fourth, and in my opinion most importantly, Go provides safeties and creates less error prone code. There are probably a ton of other reasons but those are just a few.
Why should one do this? It doesn't worth the hassle.

The effort you will put on doing this, you can just learn typescript (which really similar to Go).
Well, about the goroutines. Rxjs. Not the same but powerful.
Sorry but I am using on daily basis Go. Sometimes is really frustrating 😂
