To get the most out of this book

To get the most out of this book, you should have intermediate-level knowledge of Golang. The book assumes that you’re familiar with Go’s syntax, data types, control flow, and other basic concepts. It focuses on more advanced topics, such as creating and testing CLI applications, using external libraries, and building and distributing binaries. If you’re new to Go, you may find the material challenging, but if you have prior experience, you’ll be able to build on your existing knowledge and take your skills to the next level.
