Mastering Kotlin

Overview of this book

Using Kotlin without taking advantage of its power and interoperability is like owning a sports car and never taking it out of the garage. While documentation and introductory resources can help you learn the basics of Kotlin, the fact that it’s a new language means that there are limited learning resources and code bases available in comparison to Java and other established languages. This Kotlin book will show you how to leverage software designs and concepts that have made Java the most dominant enterprise programming language. You’ll understand how Kotlin is a modern approach to object-oriented programming (OOP). This book will take you through the vast array of features that Kotlin provides over other languages. These features include seamless interoperability with Java, efficient syntax, built-in functional programming constructs, and support for creating your own DSL. Finally, you will gain an understanding of implementing practical design patterns and best practices to help you master the Kotlin language. By the end of the book, you'll have obtained an advanced understanding of Kotlin in order to be able to build production-grade applications.

Understanding why Kotlin was designed with interop in mind

Kotlin's interop experience has been important from the beginning. The language was born with the requirement of tight integration with existing JVM tooling. In this section, we'll explore why interop has always been integral to the Kotlin story and how it is achieved.

Why is interop so important for Kotlin?

As discussed in Chapter 1, A New Challenger Approaches, Kotlin was created by JetBrains, best known for creating terrific development tools such as IntelliJ IDEA. JetBrains has explicitly expressed several motivations for creating the language including the following:

  • Wanting a more productive language for the JVM than what was then available with Java...
