Go (Golang) for Beginners: Complete Course

"Go (Golang) for Beginners: Complete Course" is a practical guide that will take you from installing the compiler to creating your own web applications and command-line utilities. The book is written in simple language and requires no prior experience in Go programming, although knowledge of the basics of any language (e.g., Python) will be a plus.

Who is this book for?

• Beginning programmers who want to learn a modern and fast language from Google.
• Developers using Python, Java, or C++ who want to switch to Go for backend development.
• Students and anyone who wants to understand how goroutines, channels, and concurrency work.

What will you learn and be able to do?

• Install Go, set up the environment, and write your first program.
• Master the syntax: variables, data types, control structures, functions, and structs.
• Understand how interfaces, error handling, and packages work.
• Learn goroutines and channels — Go's main features for parallel task execution.
• Learn to write tests and run benchmarks.
• Create a full-fledged HTTP server, work with JSON, databases, and files.
• Learn how to build and publish projects using Go Modules.

The book's structure is built on the "from simple to complex" principle. Each chapter contains theory, code examples, and exercises to reinforce the material. At the end of the course, you will create a mini-project — a REST API for notes, which you can further develop on your own.

This book will be your reliable guide to the world of Go. You won't just read theory; you will immediately apply your knowledge in practice. After reading, you will be able to confidently write utilities, web services, and even small microservices in Go.

Why choose this book? The author is an experienced developer who has personally gone from a beginner to a team lead in Go projects. All examples are tested on the current version of Go (1.22+), and complex concepts are explained without unnecessary academic jargon.
