Functional Kotlin

Learn how to apply Functional Programming with Kotlin to real-life projects with popular libraries like Arrow.

Key Features

• Focus on the functional aspects of Kotlin and identify the advantages that functional programming brings to the table and the associated coding benefits,
• Implement common functional programming design patterns and techniques.
• Learn to combine OOP and Reactive Programming with Functional Programming and how RxKotlin and funkTionale can help you implementing Functional Programming in Kotlin

Book Description

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.
