Overview of this book

Often referred to (incorrectly) as Golang, Go is the high-performance systems language of the future. Mastering Go, Second Edition helps you become a productive expert Go programmer, building and improving on the groundbreaking first edition. Mastering Go, Second Edition shows how to put Go to work on real production systems. For programmers who already know the Go language basics, this book provides examples, patterns, and clear explanations to help you deeply understand Go’s capabilities and apply them in your programming work. The book covers the nuances of Go, with in-depth guides on types and structures, packages, concurrency, network programming, compiler design, optimization, and more. Each chapter ends with exercises and resources to fully embed your new knowledge. This second edition includes a completely new chapter on machine learning in Go, guiding you from the foundation statistics techniques through simple regression and clustering to classification, neural networks, and anomaly detection. Other chapters are expanded to cover using Go with Docker and Kubernetes, Git, WebAssembly, JSON, and more. If you take the Go programming language seriously, the second edition of this book is an essential guide on expert techniques.

Title Page


  • Write your own interface and use it in another Go program. Then state why your interface is useful.
  • Write an interface for calculating the volume of shapes with three dimensions, such as cubes and spheres.
  • Write an interface for calculating the length of line segments and the distance between two points in the plane.
  • Explore reflection using your own example.
  • How does reflection work on Go maps?
  • If you are good at mathematics, try to write an interface that implements the four basic mathematical operations for both real numbers and complex numbers. Do not use the complex64 and complex128 standard Go types – define your own structure for supporting complex numbers.
