Preface

Welcome to Learning ClojureScript!

ClojureScript is an exciting new language that leverages Clojure's familiar syntax for the JavaScript runtime. This means that ClojureScript, like JavaScript, is a tool to help you write software applications that can either run in a client-side (browser) or server-side environment. This also means that ClojureScript inherits all of the wonderful benefits of Clojure, including Lisp macros, immutable and high-performance data structures, and beautiful functional syntax.

This book aims to serve as an introduction to both the core and advanced concepts of ClojureScript development with the ultimate objective of teaching you how to build single-page web applications. Whatever your background and prior level of experience with either Clojure or ClojureScript, it is our hope that this book will prove to be an invaluable aid to you in learning how to develop ClojureScript programs for the modern web.

We've structured the book in such a way as to take you through on a soft progression. Beginning with the basics of getting your interactive environment set up, we'll take you all the way through advanced subjects such as logic programming and designing your applications to use Om, a ClojureScript wrapper for Facebook's React framework. By the end of this book, you should have a deep understanding of the complete process of developing modern single-page web apps with ClojureScript, and you should feel comfortable writing applications that you know how to configure and deploy in production environments.
