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.

This book is for developers who would like to gain deeper understanding of how Kotlin works under the hood. The material doesn't depend on a certain platform of framework, but it focuses on Java Virtual Machine. This book doesn't cover topics about Kotlin to JavaScript feature and Kotlin/Native. It's a good choice for client-side developers because it contains examples with user interfaces and multithreaded environments.

, Identifying Performance Bottlenecks , covers the reasons for performance issues and how they can impact the user experience and performance of the whole software product. It is an overview of the issues this book aims to resolve, and prepares the reader for the details of these issues in subsequent chapters.

, Identifying Performance Issues , presents p erformance as one of the leading challenges you will encounter while building any software application. Response speed is one of the critical criteria to analyze performance issues, and it closely correlates with the success of that software in the market. We can use different parameters to identify problems depending on the architecture and what technology is used in the implementation.

, Learn How to Use Profiling Tools , introduces various techniques of troubleshooting application code. We will look at the different profiling tools that measure space of memory, the frequency and duration of function calls, and which software is included in the IntelliJ IDEA platform for this purpose.
