Preface

Kotlin is a statically typed programming language that is designed to interoperate with Java code. Since the kotlinc compiler generates the same bytecode as javac, migrating to a new code base doesn't require a lot of effort. Kotlin is a modern language that contains many features from different paradigms that allow you to write concise and safe code. In light of all these points, Kotlin is growing in popularity and increasing in the number of developers who use it.

The book starts by analyzing different performance metrics and debugging tools that help us to identify performance bottlenecks. It's important to understand how Kotlin and its modern features work under the hood; that's why we will inspect a lot of bytecode in the book. We will learn how to benchmark our code and avoid different types of resource leaks. The book ends with best practices that will help you to sum up all things that you've learned.
