Who this book is for

This book is primarily intended for developers who have learned how to write sequential Scala programs, and wish to learn how to write correct concurrent programs. The book assumes that you have a basic knowledge of the Scala programming language. Throughout this book, we strive to use the simple features of Scala in order to demonstrate how to write concurrent programs. Even with an elementary knowledge of Scala, you should have no problem understanding various concurrency topics.

This is not to say that the book is limited to Scala developers. Whether you have experience with Java, come from a .NET background, or are generally a programming language aficionado, chances are that you will find the content in this book insightful. A basic understanding of object-oriented or functional programming should be a sufficient prerequisite.

Finally, this book is a good introduction to modern concurrent programming in the broader sense. Even if you have the basic knowledge about multithreaded computing, or the JVM concurrency model, you will learn a lot about modern, high-level concurrency utilities. Many of the concurrency libraries in this book are only starting to find their way into mainstream programming languages, and some of them are truly cutting-edge technologies.
