Mastering Go is truly a great resource for learning and mastering the Go programming language. I don't use Go professionally but have always wanted to really learn it well to no avail. I decided to finally sit down and spend some focused time with this book and few distractions to patch gaps in the knowledge I've acquired over the years and have finally been able to grasp concepts that evaded me previously. I'm particularly interested in Go's concurrency model which seemed so mysterious before but has finally clicked with the help of this book. One piece of advice for anyone using this book to learn Go is to download the source code when it's omitted for brevity in a chapter but type up as much as you can on your own while reading the relevant explanations given by the authors. What I really love about Mastering Go is that code is not shown in its entirety and then explained from the top down; it's explained (mostly) line by line which helps a lot when coming from a language like JavaScript or Ruby (like me), which oftentimes can be explained top down with no loss of understanding. Go's a different beast which is what makes it such a great language to learn. Like any language, it requires dedication to really learn properly, but the Go team has managed to create an amazingly terse language to solve a variety of programming challenges, keeping performance in mind all along. I highly recommend learning Go and absolutely recommend Mastering Go as a resource in that adventure.

“I find the book easy to follow and easy to read. Lots of practical examples and exercises at the end of each chapter. Overall, a great good that is highly recommended!”

Wer bereits etwas Go kennt und nun den professionellen Umgang mit der Sprache erlernen möchte, findet hier wertvolle Anregungen. Ebenso derjenige, der bereits erfahren in einer anderen Programmiersprache ist und nun umsteigt. Wer nie zuvor programmiert hat, sollte sich ein anderes Werk aussuchen.

I like the clarity and depth of coverage in this book, the many different topics that are addressed, and the numerous code examples. I have been wanting to elevate my skills above the first-floor level in Go, and this updated third edition of "Mastering Go" is helping me get there. To be honest, I have played with Go several times since it first appeared, but my computer work has involved JavaScript, Angular, MEAN stacks, Python, R and others. Go has kept getting pushed aside. Now, however, Go often makes it into the top-10 rankings in surveys of the most popular computer languages. So, I want to know more and get better at working with it. This third edition of "Mastering Go" is helping me do that. Note: There is a noticeable UNIX bias in some of the discussions--the author, after all, is a UNIX systems engineer who has written other books about Go. In a paragraph titled "Why UNIX and not Windows?", he writes: "You might ask why we're talking about UNIX...and not discussing Microsoft Windows as well. There are two main reasons for this. The first reason is that most Go programs will work on Windows machines without any code changes, because Go is portable by design--this means you should not worry about the operating system you are using." I haven't tried all of his code examples yet on my Windows machine, but I've tried quite a few, and they work exactly as described in the book. I also haven't yet tried them on my Linux computer. But Linux sites assure me Go will work there, too. Bottom line: This book is meeting my current need to gain more skills at working with Go, and I recommend it to others who have gotten past "Hello, World!" and some other basic Go programs in beginner's books.

Definitely an excellent read on modern systems and network programming that's on a very short list of necessary Go programming language books. I highly recommend it!
