The Way to Go: A Thorough Introduction to the Go Programming Language

I would not suggest buying this book. Looking at others reviews that this is for beginners, I bought this. After reading 100 pages, I still don't feel like I'm learning anything from this book. I google every command the author writes about to understand what is going on. I've learnt more by googling than through the book. For example, "iota" the author just introduces that when talking about constants, but never explains what it does, or gives an example how it works. I had to google that for find out(not that I'm complaining but I paid for this book.) And there are no examples that explain how stuff are implemented, I'd suggest you spend money on other authors.

The book provides a lengthy and comprehensive introduction to the Go programming language. It assumes a prior knowledge of programming in order to illustrate the nature of Go. Although the manuscript could of used a couple of proof readers to catch typos and gramatical errors the book is excellent.

Great for beginning. Has good code examples and talks about many aspects of writing go code. Rather detailed and monotonous at times but usually has hidden gems of insight.
