The perfect starting point for your journey into Scala and functional programming. Summary In Get Programming in Scala you will learn: Object-oriented principles in Scala Express program designs in functions Use types to enforce program requirements Use abstractions to avoid code duplication Write meaningful tests and recognize code smells 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 the perfect starting point for developers with some OO knowledge who want to learn Scala and pick up a few FP skills along the way. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications. About the technology Scala developers are in high demand. This flexible language blends object-oriented and functional programming styles so you can write flexible, easy-to-maintain code. Because Scala runs on the JVM, your programs can interact seamlessly with Java libraries and tools. If you’re comfortable writing Java, this easy-to-read book will get you programming with Scala fast. About the book Get Programming with Scala is a fast-paced introduction to the Scala language, covering both Scala 2 and Scala 3. You’ll learn through lessons, quizzes, and hands-on projects that bring your new skills to life. Clear explanations make Scala’s features and abstractions easy to understand. As you go, you’ll learn to write familiar object-oriented code in Scala and also discover the possibilities of functional programming.
