The Go Programming Language is the authoritative resource for any programmer who wants to learn Go It shows how to write clear and idiomatic Go to solve real world problems The book does not assume prior knowledge of Go nor experience with any specific language so youll find it accessible whether youre most comfortable with JavaScript Ruby Python Java or C The first chapter is a tutorial on the basic concepts of Go introduced through programs for file I O and text processing simple graphics and web clients and servers Early chapters cover the structural elements of Go programs syntax control flow data types and the organization of a program into packages files and functions The examples illustrate many packages from the standard library and show how to create new ones of your own Later chapters explain the package mechanism in more detail and how to build test and maintain projects using the go tool The chapters on methods and interfaces introduce Gos unconventional approach to object oriented programming in which methods can be declared on any type and interfaces are implicitly satisfied They explain the key principles of encapsulation composition and substitutability using realistic examples Two chapters on concurrency present in depth approaches to this increasingly important topic The first which covers the basic mechanisms of goroutines and channels illustrates the style known as communicating sequential processes for which Go is renowned The second covers more traditional aspects of concurrency with shared variables These chapters provide a solid foundation for programmers encountering concurrency for the first time The final two chapters explore lower level features of Go One covers the art of metaprogramming using reflection The other shows how to use the unsafe package to step outside the type system for special situations and how to use the cgo tool to create Go bindings for C libraries The book features hundreds of interesting and practical examples of well written Go code that cover the whole language its most important packages and a wide range of applications Each chapter has exercises to test your understanding and explore extensions and alternatives Source code is freely available for download from http gopl io and may be conveniently fetched built and installed using the go get command
