Head First Go

What will you learn from this book?

Go makes it easy to build software that’s simple, reliable, and efficient. And this book makes it easy for programmers like you to get started. Google designed Go for high-performance networking and multiprocessing, but― like Python and JavaScript―the language is easy to read and use. With this practical hands-on guide, you’ll learn how to write Go code using clear examples that demonstrate the language in action. Best of all, you’ll understand the conventions and techniques that employers want entry-level Go developers to know.

Why does this book look so different?

Based on the latest research in cognitive science and learning theory, Head First Go uses a visually rich format to engage your mind rather than a textheavy approach that puts you to sleep. Why waste your time struggling with new concepts? This multisensory learning experience is designed for the way your brain really works.

About the Author

Jay McGavren was doing automation for a hotel services company when a colleague introduced him to Programming Perl (a.k.a. the Camel Book). It made him an instant Perl convert, as he liked actually writing code instead of waiting for a 10-person development team to configure a build system. It also gave him the crazy idea to write a technical book someday.

In 2007, with Perl sputtering, Jay was looking for a new interpreted language. With its strong object-orientation, excellent library support, and incredible flexibility, Ruby immediately won him over. He’s since used Ruby for two game libraries, a generative art project, in support of a Java development job, and as a Ruby on Rails freelancer. He’s been using Rails in the online developer education space since 2011.
