Learn Golang Essentials in a Weekend! Go is one of the most powerful, and yet the simplest, modern programming languages. We go through all important features of the modern Go programming language (as of 1.18 and 1.19 - 2022), including generics!! Why Go? * Go is a simple, easy to learn and use, beginner-friendly high-level programming language. * Go is suitable for low-level systems programming, traditionally done by low level languages like C. * Go is one of the most popular languages in modern Web services and application development. * Go is one of the most widely used CLI application languages for system administration and network management. * Go is fun! Although the book is written as a reference, you can read it more or less from beginning to end and you should be able to get the overall picture of the Go language (but not necessarily all the gory details) if you have some prior experience with programming in Go or other similar C-style languages. The book covers * Go toolchain. Workspaces, modules. * Go program execution model. Packages. * Variable, constant declarations. * Builtin types, builtin functions. * Structs, interfaces. Generic types. * Functions, methods. Generic functions. * Expressions and statements. * Goroutines. The book also includes a bonus chapter on generics for people who are new to programming with the parameterized types. Generics brings the power of the modern type system to the Go programming language. You won't be able to program effectively in Go without fully utilizing generics moving forward.

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 you’ll find it accessible whether you’re 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 Go’s 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.
