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.

In this chapter, we talked about code testing, code optimization, and code profiling. Near the end of the chapter, you learned how to find unreachable code and how to cross-compile Go code. The go test command is used to test and benchmark Go code, as well as offering extra documentation with the use of example functions.

Although the discussion of the Go profiler and go tool trace is far from complete, you should understand that with topics such as profiling and code tracing, nothing can replace experimenting and trying new techniques on your own!

In the next chapter, Chapter 12The Foundations of Network Programming in Go, we will start talking about network programming in Go, which involves programming applications that work over TCP/IP computer networks, which includes the Internet. Some of the subjects in the next chapter are the net/http package, creating web...
