Learning Go Programming

Overview of this book

The Go programming language has firmly established itself as a favorite for building complex and scalable system applications. Go offers a direct and practical approach to programming that let programmers write correct and predictable code using concurrency idioms and a full-featured standard library. This is a step-by-step, practical guide full of real world examples to help you get started with Go in no time at all. We start off by understanding the fundamentals of Go, followed by a detailed description of the Go data types, program structures and Maps. After this, you learn how to use Go concurrency idioms to avoid pitfalls and create programs that are exact in expected behavior. Next, you will be familiarized with the tools and libraries that are available in Go for writing and exercising tests, benchmarking, and code coverage. Finally, you will be able to utilize some of the most important features of GO such as, Network Programming and OS integration to build efficient applications. All the concepts are explained in a crisp and concise manner and by the end of this book; you would be able to create highly efficient programs that you can deploy over cloud.

Objects in Go

The lengthy introductory material from the previous sections was the setup to lead to the discussion of objects in Go. It has been mentioned that Go was not designed to function as traditional object-oriented language. There are no object or class keywords defined in Go. So then, why are we discussing objects in Go at all? Well, it turns out that Go perfectly supports object idioms and the practice of object-oriented programming without the heavy baggage of classical hierarchies and complex inheritance structures found in other object-oriented languages.

Let us review some of the primordial features usually attributed to an object-oriented language in the following table.

Object feature



Object: A data type that stores states and exposes behavior


In Go all types can achieve this. There is no special type called a class or object to do this. Any type can receive a set of method to define its behavior, although the struct type comes the closest to what is commonly...
