This international bestseller has been revised with new exercises, annotations, and full coverage of Scala 3.In Functional Programming in Scala, Second Edition you will learn how to:Recognize and write purely functional code Work with errors without using exceptions Work with state and concurrency Interact with functional structures that define common behaviors Write code that performs I/O without sacrificing functional programmingFunctional Programming in Scala has helped over 30,000 developers discover the power of functional programming. Youll soon see why reviewers have called it mindblowing! The book smooths the complexity curve of functional programming, making it simple to understand the basics and intuitive to progress to more advanced topics. Concrete examples and exercises show you FP in the real world and reveal how it can improve your everyday coding practices. This second edition comes packed with the latest standards of FP, as well as full code updates to Scala 3, and its new language features.Foreword by Daniel Spiewak.Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.About the TechnologyFunctional code is easy to test, reuse, and parallelize, and its practically immune to whole categories of state-related bugs. With its strong functional features, familiar syntax, and seamless interoperability with Java, theres no better place to start learning functional programming than the flexible Scala language.About the BookIn Functional Programming with Scala, Second Edition youll learn functional programming from first principles. Hands-on exercises and examples make it easy to start thinking and coding functionally. This revised edition contains extensive exercise annotations to help you explore FP in depth, along with steps to build your own functional libraries in Scala. Once the functional lightbulb goes on, youll never look at coding the same way again.Whats InsideRecognize and write purely functional code Work with errors without using exceptions Work with state and concurrency Interact with functional structures that define common behaviorsAbout the ReaderFor Java or Scala programmers.
