Preface

Welcome to the fourth edition of Mastering Go! As the Go programming language continues to evolve and gain popularity, I am delighted to present an updated edition of this book.

In the rapidly changing landscape of technology, Go has emerged as a language of choice for building scalable, performant, and maintainable software. Whether you are a seasoned Go developer looking to deepen your expertise or a newcomer eager to master the intricacies of the language, this book is your comprehensive guide.

If you have an older edition of Mastering Go, apart from the first edition, which is now pretty old, do not throw it away just because Mastering Go, Fourth Edition, is out. Go has not changed that much and both the second and third editions can still be useful and relevant. However, Mastering Go, Fourth Edition, is better in many aspects than all previous editions and includes information about the latest Go versions, which you are not going to find in the previous editions of the book.

There exist many exciting topics in this latest edition, including writing RESTful services, writing a statistics application, and working with eBPF, as well as an entirely new chapter on fuzz testing and observability.

I tried to include the right amount of theory and hands-on content—but only you, the reader, can tell if I have succeeded or not. Try to do the exercises located at the end of each chapter and do not hesitate to contact me about ways or ideas to make future editions of this book even better.

Thank you for choosing to pick up Mastering Go, Fourth Edition. Let us dive in and unlock the full potential of Go together. Happy coding!
