Scala in Action

Summary

Scala in Action is a comprehensive tutorial that introduces Scala through clear explanations and numerous hands-on examples. Because Scala is a rich and deep language, it can be daunting to absorb all the new concepts at once. This book takes a "how-to" approach, explaining language concepts as you explore familiar programming challenges that you face in your day-to-day work.

About the Technology

Scala runs on the JVM and combines object-orientation with functional programming. It's designed to produce succinct, type-safe code, which is crucial for enterprise applications. Scala implements Actor-based concurrency through the amazing Akka framework, so you can avoid Java's messy threading while interacting seamlessly with Java.

About this Book

Scala in Action is a comprehensive tutorial that introduces the language through clear explanations and numerous hands-on examples. It takes a "how to" approach, explaining language concepts as you explore familiar programming tasks. You'll tackle concurrent programming in Akka, learn to work with Scala and Spring, and learn how to build DSLs and other productivity tools. You'll learn both the language and how to use it.

Experience with Java is helpful but not required. Ruby and Python programmers will also find this book accessible.

Even within a single application, programming problems often lend themselves to a particular style of programming - functional, imperative, dynamic - but most languages require you to choose a single approach before you start. Scala is a statically typed, JVM-compatible programming language that blends the object oriented and functional programming models, giving one the flexibility to use the right approach for each specific case.
