I dedicate this book to all those who are working hard every day to find the right balance between the feeling of Yes, I got this! and What am I even doing? and continuing the battle that we call living.

John Arundel is a well-known Go writer, teacher, and mentor. He has been writing software for 40 years, and he thinks he's finally starting to figure out how to do it. You can find out more about John at bitfieldconsulting.com.

John lives in a fairytale cottage in Cornwall, England, surrounded by woods, wildlife, and a slowly deepening silence.

I want to thank the entire team at Wiley that made this book possible. First, Jim Minatel, who responded to my initial email expressing interest in publishing a book with Wiley. Jim then connected me with Devon Lewis, with whom I discussed the book proposal and who was instrumental in commissioning this book and overseeing the entire process. Next, I would like to thank Gary Schwartz, who in his capacity as project manager guided me throughout the entire project, ensuring that I was on track with my delivery of the chapters. Thank you, Judy Flynn, for your meticulousness in your role as the copyeditor. Finally, thank you, Barath Kumar Rajasekaran, for overseeing the proofreading process. Working with this team of fine folks was my version of a Ulysses pact.

John Arundel was kind enough to accept my request to be the technical reviewer of this book, and his insights and comments greatly helped to make the book better as well as making me a better Go programmer.

I want to thank all the community members on the Golang nuts and gRPC mailing lists who were always helpful in answering my questions and clarifying my doubts. My initial days of learning Go were mostly spent copying and pasting code from the Go by example project at https://gobyexample.com; hence I would like to acknowledge the efforts of the creator and maintainers of this project for their super-helpful resource.

Finally, I appreciate the efforts of the folks at Cooperpress who publish Golang Weekly (and the authors of the articles to which they linked) and The Go Time podcast. They helped me in learning Go and staying up to date with the latest happenings in the Go community.

Since its announcement to the community, and the compatibility promise of the 1.0 release, the Go language has been used to write scalable and high-impact software programs ranging from command-line applications and critical infrastructure tools to large-scale distributed systems. The Go language has made a huge contribution to the growth of a number of modern software success stories. For a number of years, my personal interest in Go has been due to its, for the lack of a better word,
