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.

Summary

In this chapter, you learned about debugging, git(1), GitHub, and interfaces, which are like contracts, and also about type methods, type assertion, and reflection in Go. Although reflection is a very powerful Go feature, it might slow down your Go programs because it adds a layer of complexity at runtime. Furthermore, your Go programs could crash if you use reflection carelessly.

You additionally learned about creating Go code that follows the principles of object-oriented programming. If you are going to remember just one thing from this chapter, it should be that Go is not an object-oriented programming language, but it can mimic some of the functionality offered by object-programming languages, such as Java and C++. This means that if you plan to develop software using the object-oriented paradigm all of the time, it would be best to choose a programming language other...
