It’s faster than Node or Python, with a better type system than either. It’s got a much easier learning curve than Rust. It has a good stdlib and tooling. Simple syntax with usually only one way to do things. Error handling has its problems but I still prefer it over Node, where a catch clause might receive just about anything as an “error”.
Am I missing a language that does this too or more? I’m not a Go fanatic at all, mostly written Node for backends in my career, but I’ve been exploring Go lately.
Given Python's substantial improvements recently, I would put it far ahead of the structural typing done in Go, personally.
Go (and lots of other languages...) wreck it on dependency management and deployment, though. :-/ As the saying goes, "it was easier to invent Docker than fix Python's tooling".
