Hello, and welcome to learning Go! It's great to have you here. The Deeper Love of Go is a book introducing the Go programming language, suitable for complete beginners, as well as those with experience programming in other languages. Includes free updates for life.

This is an early access edition, so it’s not yet complete, but updates will be published regularly, and you can read it as a work in progress.

Reviews

⭐⭐⭐⭐⭐ “Takes a very different approach from other beginner Go books, putting much more emphasis on mastering the fundamentals, rather than bewildering the reader with irrelevant detail.”
—Kris Broadie

About the book

This book assumes no previous knowledge of programming, and gently introduces you to Go step by step, challenging you to apply each new concept as you learn it. If you’ve used Go before but feel somehow you skipped something important, this book will build your confidence in the fundamentals. Take your first steps toward mastery with my fun, readable, and easy-to-follow guide.

Throughout the book we'll be working together to develop a fun and useful project in Go: an online bookstore called Happy Fun Books. You’ll learn how to use Go to store data about real-world objects such as books, how to write code to manage and modify that data, and how to build useful and effective programs around it.

Each chapter introduces a new feature or concept, and sets you some goals to achieve, with complete, step-by-step explanations of how to solve them, and full code listings with accompanying tests.

What you’ll learn

By reading this book and working through all the challenges and exercises, you'll learn:

• How to write tests in Go and how to develop projects guided by tests

• How to manage data in Go using built-in types, user-defined struct types, and collections such as maps and slices

• How to use objects to model problems in Go, and how to add behaviour to objects using methods

• How to use pointers to write methods for objects, and how to use types and validation to make your Go packages a delight to use

Even more importantly, you’ll learn a simple, fun, and effective way to approach software engineering projects in Go. Even though the material is beginner-friendly, you’ll be mastering some advanced techniques, and learning to design modules, packages, and APIs. These are essential skills in any modern software engineering role.
