Part 3. Advanced steps

These last 2 chapters lead you through advanced steps in Scala.

One of the most exciting features of Scala is that it runs on the JVM. The benefit of running on a JVM, as you know by this point, is that you can integrate with other languages on it and take advantage of all the frameworks and tools built into other JVM languages. Chapter 11, while it encourages you to think Scala first, covers the interoperability between Scala and Java.

Chapter 12 introduces Akka, a Scala toolkit that allows you to build nextgeneration, event-based, fault-tolerant, scalable, and distributed applications for the JVM.

To understand how the individual pieces of Akka fit together, you’re going to build a large real-time product search application using Akka called Akkaoogle. This application is similar to what used to be called Froogle.
