Functional Kotlin

Overview of this book

Functional programming makes your application faster, improves performance, and increases your productivity. Kotlin supports many of the popular and advanced functional features of functional languages. This book will cover the A-Z of functional programming in Kotlin. This book bridges the language gap for Kotlin developers by showing you how to create and consume functional constructs in Kotlin. We also bridge the domain gap by showing how functional constructs can be applied in business scenarios. We’ll take you through lambdas, pattern matching, immutability, and help you develop a deep understanding of the concepts and practices of functional programming. If you want learn to address problems using Recursion, Koltin has support for it as well. You’ll also learn how to use the funKtionale library to perform currying and lazy programming and more. Finally, you’ll learn functional design patterns and techniques that will make you a better programmer.By the end of the book, you will be more confident in your functional programming skills and will be able to apply them while programming in Kotlin.

Chapter 7. Asynchronous Programming with Coroutines

Today's software development landscape makes asynchronous processing one of the most important topics. The ever-increasing number of processors and cores and the massive consumption of external services (which has grown in recent years with the adoption of microservices architectures) are some of the factors that we should keep an eye on and strive to use a good asynchronous approach.

Kotlin's implementation of coroutines is an excellent tool to build asynchronous applications.

In this chapter, we'll cover the following topics:

  • Coroutines
  • Alternative approaches
  • Asynchronous processing
  • Channels and actors
