In this chapter, we studied what concurrent programming is and why Scala is a good language for concurrency. We gave a brief overview of what you will learn in this book, and how the book is organized. Finally, we stated some Scala preliminaries necessary for understanding the various concurrency topics in the subsequent chapters. If you would like to learn more about sequential Scala programming, we suggest that you read the book Programming in Scala, Martin Odersky, Lex Spoon, and Bill Venners, Artima Inc.
In the next chapter, we will start with the fundamentals of concurrent programming on the JVM. We will introduce the basic concepts in concurrent programming, present the low-level concurrency utilities available on the JVM, and learn about the Java Memory Model.
