Scala Functional Programming Patterns

Grok and perform effective functional programming in ScalaAbout This BookUnderstand functional programming patterns by comparing them with the traditional object-oriented design patternsWrite robust, safer, and better code using the declarative programming paradigmAn illustrative guide for programmers to create functional programming patterns wi... more »th ScalaWho This Book Is ForIf you have done Java programming before and have a basic knowledge of Scala and its syntax, then this book is an ideal choice to help you to understand the context, the traditional design pattern applicable, and the Scala way. Having previous knowledge of design patterns will help, though it is not strictly necessary.What You Will LearnGet to know about idioms by looking at the various mainstream languages and the value that Scala's FP idioms bring to the tableSolve day-to-day programming problems using object-oriented idiomsExpress patterns simply and elegantly using Scala's power-packed featuresTame complexity by embracing the events and call-back modelAvoid creating complex concurrent systems using the Akka library and Active ObjectsApply recursive thinking and understand how to create solutions without mutationReuse existing code to compose new behaviorCombine the object-oriented and functional programming approaches for effective programming using ScalaIn DetailScala is used to construct elegant class hierarchies for maximum code reuse and extensibility and to implement their behavior using higher-order functions. Its functional programming (FP) features are a boon to help you design "easy to reason about" systems to control the growing software complexities. Knowing how and where to apply the many Scala techniques is challenging. Looking at Scala best practices in the context of what you already know helps you grasp these concepts quickly, and helps you see where and why to use them.This book begins with the rationale behind patterns to help you understand where and why each pattern is applied. You will discover what tail recursion brings to your table and will get an understanding of how to create solutions without mutations. We then explain the concept of memorization and infinite sequences for on-demand computation. Further, the book takes you through Scala's stackable traits and dependency injection, a popular technique to produce loosely-coupled software systems.You will also explore how to currying favors to your code and how to simplify it by de-construction via pattern matching. We also show you how to do pipeline transformations using higher order functions such as the pipes and filters pattern. Then we guide you through the increasing importance of concurrent programming and the pitfalls of traditional code concurrency. Lastly, the book takes a paradigm shift to show you the different techniques that functional programming brings to your plate.This book is an invaluable source to help you understand and perform functional programming and solve common programming problems using Scala's programming patterns.
