Overview of this book

The Android team has announced first-class support for Kotlin 1.1. This acts as an added boost to the language and more and more developers are now looking at Kotlin for their application development. This recipe-based book will be your guide to learning the Kotlin programming language. The recipes in this book build from simple language concepts to more complex applications of the language. After the fundamentals of the language, you will learn how to apply the object-oriented programming features of Kotlin 1.1. Programming with Lambdas will show you how to use the functional power of Kotlin. This book has recipes that will get you started with Android programming with Kotlin 1.1, providing quick solutions to common problems encountered during Android app development. You will also be taken through recipes that will teach you microservice and concurrent programming with Kotlin. Going forward, you will learn to test and secure your applications with Kotlin. Finally, this book supplies recipes that will help you migrate your Java code to Kotlin and will help ensure that it's interoperable with Java.

Introduction


Functions are the building blocks of any code. They help make our programs more modular, secure, and easy to understand. Functions are crucial in object-oriented programming as they play an important role in abstraction and encapsulation (two very important design principles). Kotlin brings a lot of updates to the way we use functions. It makes functional programming easier with the help of chaining and lambdas. In this chapter, we will learn recipes that will help us work with functions. So let's get started!
