Scala is a multi-style programming language for the JVM that supports both object-oriented and functional programming. Master Scala, and you'll be well-equipped to match your programming approach to the type of problem you're dealing with. Packed with examples and exercises, Get Programming with Scala is perfect starting point for developers with some OO knowledge who want to learn Scala and pick up a few FP skills along the way.

About the Technology

Although it's a relative newcomer, Scala turned out to be the right language at the right time, opening up the world of functional programming to the JVM. Scala looks a lot like Java, and it interacts seamlessly with familiar Java libraries and tools. Since it fully supports functional programming, Scala gives you the freedom to choose the right programming style exactly when it benefits you. Scala can be daunting at first, especially if you're seeing FP ideas for the first time. Fortunately, with the examples and exercises in this book, you'll get over the initial learning hump quickly and start doing interesting projects before you know it!

About the book

Get Programming with Scala teaches you the core skills you'll need to code with Scala. This book lives up to its name! You'll learn the ins and outs of Scala by actually programming with it, thanks to the practical examples, exercises, and easy-to-follow lessons. You'll start by reviewing OOP concepts in the Scala language. Then, example-by-example, you'll gradually open up the world of functional programming. You'll explore functions and types and learn how to combine them to create powerful, flexible abstractions. Along the way, you'll learn some Scala testing and get an intuition for sniffing out and fixing code that doesn't smell quite right.

What's inside

  • Learn to express OO principles in Scala
  • Express your program designs in functions
  • Make use of types to enforce program requirements
  • Use abstractions to avoid code duplication
  • Write meaningful tests and recognize code smells

About the reader

Written for developers with some prior experience in an OOP language like Java or C#. No experience with Scala or functional programming is needed.
