Go is excellent for writing CLI's and network services since it comes with built-in cross-platform sockets, HTTP, easy-concurrency, crypto, SSL and a comprehensive standard library. You don't need an overarching framework. You can pick and choose helper libs if you really need them. Doing the same in something like C++ or Java is a headache simply because the standard library is not sufficient and you waste valuable time in framework and library decision making. I learnt golang through books. The traditional GOPL, and OReilly's "Concurrency in Go". "Go Programming Blueprints 2nd Edition" shows how to implement several projects using (mostly) the Go standard library. (Sometimes developer time is not always the top most consideration though. There is one internal service that we refactored from Python -> Golang -> C++ for low-latency and low-memory performance.) Not tried Rust yet.
