The Ultimate Go Notebook is the official companion book for the Ardan Labs Ultimate Go class. With this book, you will learn how to write more idiomatic and performant code with a focus on micro-level engineering decisions. This notebook has been designed to provide a reference to everything mentioned in class, as if they were your own personal notes.Our classes challenge every student to think about what they are doing and why and so does this book.- The first chapter helps you prepare your mind by establishing the mental models and design philosophy for the material you are about to review.- You will learn about the mechanics and semantics behind types, decoupling, error handling, concurrency, and more.- GENERICS! Learn about the new syntax coming to Go 1.18 for writing generic functions and types.- Four chapters on profiling, tracing, and stack traces help you learn critical debugging skills that will make you a more productive Go developer.- The last chapter features the many blog posts that are referenced throughout the book. If you have taken the class before, this notebook will be an invaluable resource for reminders on the content. If you have never taken the class, there is still tremendous value in this book as it covers more advanced topics not found in other books today."If you want to be a better Go developer, code reviewer, designer and architect, this is the book you want."When coming from another language, developers often struggle to grasp the fundamentals that make Go useful and unique. This book builds layers of foundational knowledge that will give you a deeper understanding into data semantics, decoupling, concurrency and tooling that is provided with the language.
