Who this book is for

This book is for programmers or software architects who are familiar with Clojure and want to learn about the language's features in detail. It is also for readers who are eager to explore popular and practical Clojure libraries.

This book does not describe the syntax of the Clojure language. You are expected to be familiar with the language, but you need not be a Clojure expert. You are also expected to know how functions are used and defined in Clojure, and have some basic knowledge about Clojure data structures such as strings, lists, vectors, maps, and sets. You must also be able to compile ClojureScript programs to JavaScript and run them in an HTML page.
