Part 1. Background and fundamentals
This opening part of the book provides some background about Go and a foundation for building applications. Chapter 1 starts with an overview of Go for those not already familiar with it.
Chapters 2 and 3 move into base components for an application. Chapter 2 provides the foundation for building an application, including working with console applications and servers, and handling configuration. Chapter 3 focuses on using goroutines. Goroutines are one of the more powerful and useful elements in Go. They’re regularly used in Go applications, and you’ll see them through the rest of this book.
