The good news is that Go is simpler than many other languages, with fewer constructs, concepts and corner cases. So after using it for a while, you will rarely bump into anything "new". Reading the language spec is great, and I have done it myself a couple of times. But, depending on your level of programming experience, it may be a bit difficult to pull useful information from the spec, and can be a bit tedious to read. For starters, I strongly suggest working through A Tour of Go <https://tour.golang.org/welcome/1>, maybe a few times. It covers almost all the language concepts. Type switches are covered in in the tour at: https://tour.golang.org/methods/16.
