About this Book


Go is an open source programming language that makes it easy to build simple, reliable, and efficient software. Although it borrows ideas from existing languages, it has a unique and simple nature that makes Go programs different in character from programs written in other languages. It balances the capabilities of a low-level systems language with some high-level features you see in modern languages today. This creates a programming environment that allows you to be incredibly productive, performant, and fully in control; in Go, you can write less code and do so much more.

Who should read this book?

This book was written for an intermediate-level developer who has some experience with other programming languages and wants to learn Go. Our goal in writing this book is to provide you an intensive, comprehensive, and idiomatic view of the language. We focus on both the specification and implementation of the language, including topics that range from language syntax, Go’s type system, concurrency, channels, testing, and more. We believe this book is perfect for anyone who wants a jump-start in learning Go as well as for those who want a more thorough understanding of the language and its internals.


The book consists of nine chapters, briefly described here:
