The Go programming language is a relatively new language born out of its creators’ frustration with the complexity of other systems programming languages, such as C++, and initially released in 2009. Since then, Go has gathered significant support, with important developments, such as Docker and Kubernetes being written in Go.

This book is an introduction to programming using Go, aimed at programmers at beginner or intermediate level. Like other books in the series, the book is divided into 24 chapters, each representing a hypothetical hour’s worth of learning. Registering the book gives access to two additional chapters that are available for download from the book’s website.

The content is broadly structured into two parts, with the first concentrating on the Go language itself while the second half is concerned with pragmatic aspects of using the language.

Early chapters describe how to obtain and install a Go environment as well as overviewing the available development tools and IDEs. The book quickly begins to acquaint the reader with Go code by introducing Go’s implementation of common programming language features such as program structure, flow control, types, structures and pointers, variables and scope, functions and exception handling. The content then focuses on key features of Go itself, including polymorphism through methods and interfaces and concurrency and synchronisation though goroutines and channels.

The second half of the book concentrates on practical aspects of using the Go language. In these chapters, the reader is introduced to Go’s module system and aspects of idiomatic Go as well as approaches to testing and debugging Go programs. There are also chapters which describe the use of Go and its libraries in developing components of web applications and performing related tasks such as processing JSON and text data.

The book is fast-paced, well written and very readable. Each chapter is structured with an introductory section outlining the chapter’s learning objectives, the chapter content itself, and a summary. Chapters contain numerous code examples, and include short ‘Q&A’ sections, quiz questions and exercises in order to help reinforce and extend learning.

The emphasis is very much on hands-on learning, with the reader being encouraged to try and experiment with short code samples. Code examples are brief enough to be quickly typed in, but they are also available for download from the book’s website.

This a great introduction to Go which can easily be read in its entirety but will also serve as a useful reference book.

It is a good book. It does not take 24 hours. It is more like 30 minutes per chapter or less. You should be done in 3 hours or so.

There is a solid introduction to the language. It covers enough ground with the usual examples you see in every "teach-yourself-a-coding-language-in-24 hours", it even includes how to work with json, create httpservers and bundle things up in a container.

I was doing golang coding of course without reading any manuals. I needed to step back and figure out why I was stuck. This helped.

Oh, don't buy this book solo, go get yourself a safaribooksonline subscription :) I found the book there.

Ce livre est facile à prendre en main et m'a permis de rapidement comprendre le Go et à apprendre à programmer avec ce langage de programmation concurrent. Les chapitres s'enchaînent pour vous apprendre progressivement les bases puis les constructions spécifiques au Go. En suivant le livre, j'ai pu rapidement devenir un débutant d'un bon niveau en Go.

Bagus untuk pengenalan awal. Hanya cukup sampai bisa scripting dan membuat perangkat lunak yang tidak kompleks. Tidak sesuai judul, empat atau enam jam fokus cukup untuk menyelesaikannya (plus latihan coding).

It has a lot of examples. You will have to google while reading this because golint command changed, and a few other packages changed.

The book provides a lot of information for beginners. I appreciate the last few chapters the most.

This is a great introduction for beginners. The author doesn't assume any prior knowledge of programming languages, and I would have preferred something more advanced. But that's fine. It's a solid introductory text with numerous code examples.

This book is meh in its content and needs serious refreshing. Avoid it if you truly want to learn Go.

• Code examples have error, making it harder to follow

End up having to go online to find the actual code

It's not 24hours but days and that is great because the book is awesome, recommended!
