12 Excellent Free Books to Learn Go

5. Learning Go by Mike Gieben

Learning GoThis book is aimed at developers with some knowledge of programming languages and how to program.

The best way to learn Go is to create your own programs. Each chapter therefore includes exercises (and answers to exercises) to acquaint you with the language. Each exercise is either easy, intermediate, or difficult.

All exercises in this book work with Go 1, the first stable release of Go.

Chapters cover:

  • Introduction – details the lineage of the language and shows the types, variables and control structures.
  • Functions – how to make and use functions.
  • Packages – functions and data are grouped together in packages. Here you’ll see how to make your own package. How to unit test your package is also described.
  • Beyond the basics – learn how to create your own data types and define functions on them (called methods).
  • Interfaces – Go does not support Object Orientation in the traditional sense. In Go the central concept is interfaces.
  • Concurrency – with the go keyword functions can be started in separate routines (called goroutines). Communication with these goroutines is done via channels.
  • Communication – how to create/read/write from and to files. And how to do networking.

7. Let’s learn Go by Big Yuuta

Lets Learn GoLet’s learn Go is an online resource which aims to introduce people to Go, and have some fun at the same time.

Learn the very basic things about Go. This includes the basic syntax for programs, how to declare variables, pointers, and how to use basic control structure.

The online book then moves on to teaching the reader how to use primitive data types and basic control structures to build composite types and functions. The book later delves deeper into functions and solving real world problems.

8. The Little Go Book by Karl Seguin

The Little Go BookThe Little Go Book is a free introduction to Google’s Go programming language. It’s aimed at developers who might not be quite comfortable with the idea of pointers and static typing. It’s longer than the other Little books, but hopefully still captures that little feeling.

Chapters include:

  • The Basics.
  • Structures.
  • Maps, Arrays and Slices.
  • Code Organization and Interfaces.
  • Tidbits – talks about a miscellany of Go’s features.
  • Concurrency.
