This book is for Clojure developers who are currently building or planning to build asynchronous and concurrent applications and who are interested in how they can apply the principles and tools of Reactive Programming to their daily jobs.

Knowledge of Clojure and leiningen—a popular Clojure build tool—is required.

The book also features several ClojureScript examples, and as such, familiarity with ClojureScript and web development in general will be helpful.

Notwithstanding, the chapters have been carefully written in such a way that as long as you possess knowledge of Clojure, following these examples should only require a little extra effort.

As this book progresses, it lays out the building blocks required by later chapters, and as such my recommendation is that you start with Chapter 1, What is Reactive Programming?, and work your way through subsequent chapters in order.

A clear exception to this is Appendix A, The Algebra of Library Design, which is optional and can be read independent of the others—although reading Chapter 8, Futures, might provide a useful background.
