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.

So, this chapter was on collections and data operations in Kotlin. We started the chapter by exploring the collection framework in Kotlin and data structure of collections, and we gradually moved towards learning the data operations and functions that Kotlin collection framework provides out of the box.

In the next chapter, we will learn how to work with functional programming, reactive programming, and OOP altogether. We believe Kotlin is the best language for this, as it lets you take the benefits of both worlds—functional programming and OOP. In the next chapter, we will see how to take advantage of this.

In the next chapter, we will also introduce ourselves to the ReactiveX framework, which is among the most popular frameworks for functional reactive programming.

So, lets move ahead; the next chapter is just a page turn away.
