I received a review copy of the book and I enjoyed it thoroughly. The author does a great job covering the Go language from the basics all the way to advanced concepts. In particularly, I appreciated the chapter on templates (coming in Go 1.18). It is one of the features I personally wait for. The author's style is very engaging. He explains the concepts concisely, yet in detail and demonstrates with code samples. I highly recommend it to beginners as well as seasoned Go developers.

Mastering Go is a book that I picked up recently, in order to develop better APIs than I was able to with Node.js. Mastering Go is designed as a book that teaches Go holistically, first teaching the fundamentals of the language, then teaching common software engineering concepts as they relate to Go, such as multithreading, testing, profiling, and writing APIs. I really liked the exercises and additional resources that the book provided at the end of each chapter, because they helped me go from writing the bare-minimum amount of Go code to cover each concept, to writingmany programs with Go to gain a deeper understanding of the language.With this book, I have learned quite a bit about Go. I have learned how to make REST APIs. With some additional study, I've even learned how to connect with databases in order to have a persistent data store linked to my API. Overall, learning Go with Mastering Go has been a pleasure, because it has taught me a new programming language, allowed me to learn exactly what I intended regarding REST APIs, and now I have a new tool in my tool belt. There's also a lot about other networking services in the book, including writing TCP and UDP clients, and working with gRPC. I believe that this information is going to come in handy for me down the line.I plan on using Go to create my own full-stack video streaming site for software demos, and learning the language via Mastering Go is going to make it fairly simple to create the REST API side of this app. I feel comfortable using Go for production-grade applications, and I hope to use it in my projects in the future.

Go is a beautiful programming language and this book makes the learning of Go easier.Have in mind that you still need to write your own programs to learn Go. No book can replace practice.

BishTechIT Nov 25, 2021

The book feels more like a journal than a tech manual. the golang use case and it's origin story is compelling.

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.
