 Go in Action introduces the Go language, guiding you from inquisitive developer to Go guru. The book begins by introducing the unique features and concepts of Go. (We assume you're up to speed with another programming language already, so don't expect to spend a lot of time rehearsing stuff you already know.) Then, you'll get hands-on experience writing real-world applications including web sites and network servers, as well as techniques to manipulate and convert data at speeds that will make your friends jealous. In the final chapters, you'll go in-depth with the language and see the tricks and secrets that the Go masters are using to make their applications perform. For example, you'll learn to use Go's powerful reflection libraries and work with real-world examples of integration with C code.
