Clojure Cookbook

Preface

The primary goal of this book is to provide mid-length examples of Clojure code that go beyond the basics, with a focus on real-world, everyday applications (as opposed to more conceptual or academic issues).

Unlike many of the other books on Clojure written to date, the organizing theme of this book is not the language itself, or its features and capabilities. Instead, it focuses on specific tasks that developers face (regardless of what language they’re using) and shows an example of how to use Clojure to solve each of those specific problems.

As such, this book is not and cannot be truly comprehensive; there are infinite possible example problems. However, we do hope we’ve documented some of the more common ones that most programmers encounter frequently, and that by induction readers will be able to learn some common patterns, approaches, and techniques that will serve them well as they design solutions for their own unique problems.

How This Book Was Written

An important thing you should understand about this book is that it is, first and foremost, a group effort. It is not authored by one or two people. It isn’t even the work of a single, well-defined group. Instead, it is the collaborative product of more than 60 of the best Clojurists from all over the world, from all backgrounds. These authors use Clojure every day on real applications, ranging from aerospace to social media, banking to robotics, AI research to e-commerce.

As such, you will see a lot of diversity in ...
