Textbook in PDF format Master Go language fundamentals, learn how to structure Go projects effectively, and deliver high-performance code using Go’s powerful concurrency model. In Go in Action, Second Edition you will learn Go language fundamentals How to set up and structure a Go software project Working with the Go type system Concurrency in Go Go’s unique approach to error handling Writing and capturing errors in your own software How to use Go’s built-in testing and observability features Go in Action, Second Edition has been fully updated to cover all the new features and idioms of the latest version of Go. In it, you’ll dive into Go's unique features and quickly get started writing real-world applications, such as websites and network servers. Recent decades have also seen the rise in popularity of the open source software movement, allowing developers across the spectrum of technology to share in innovation, quality and collective oversight. Today’s programmers and companies believe more than ever in the power of open source software, and the desire to participate in this movement only continues to grow. Go has sought to meet all of these needs. As a language, it provides developers with refined abstractions around concurrency and a powerful runtime to make efficient use of it with the resources at hand. As a programming environment, it provides robust tooling to make inspection, observation, dependency resolution and code sharing sane and easy. As an enterprise language, it has adopted a simple, opinionated syntax and coding standards as first principles to enable efficient collaboraction across large teams. Finally, the project has embraced the open source ethos, with all work in the open for all to see, while also integrating with public open source repositories and revision control systems such as Github. In this book, you will explore these features and gain a sense of the many decisions that have shaped the language, so that you can undersdand not only how the language works, but a bit more about why it works the way it does. Go was not developed in isolation, but as a response to the perceived deficits in programming environments that existed at the time of its creation. Its design is practical, and informed by many collective decades of programming experience, in a variety of environments and languages.
