Full review
Verdict: It’s a fairly reasonable book on Go. It’s not for dummies and it’s well written and to the point. It’s a pretty standard description of a language for anyone who knows how to program, but it’s not as obvious as you might like in the early chapters. It doesn’t do a good job selling the benefits of Go as a language, and it doesn’t deal with Go as a system programming language. You might want a copy if some of the practical examples are things you want to do.
