I used "A Tour of Go"[0] which was enough having come from C/C++ and Java backgrounds. Coming from a JS background you would be missing some context about the differences between variables, data, and references/pointers. Eventually the distinction between concurrency and async might need some brushing-up on as well.

Learning Python should be much more straightforward as the way it runs is more similar to JS.
