Kotlin is a powerful language that has already revolutionized Android and backend development, but it also has powerful support for functional programming. Its amazing features, like functional collection processing, DSL builders, scope functions, or context receivers, help developers achieve intuitive and expressive functional syntax. Additionally, Kotlin’s extensibility allows libraries like Arrow to promote an even more functional style, all while keeping proper type safety, stability, and performance. Thanks to all this, Kotlin has become the promised land for many developers who are passionate about functional programming in real-life applications.
This book is about Kotlin’s functional programming features. It covers the essentials first and then builds on them. It presents important and practical topics like collection processing, function references, scope functions, DSL usage and creation, and context receivers.
This book is perfect for developers who know the basics of Kotlin and want to learn more advanced features. Math knowledge is NOT required to understand and benefit from this book. It is a natural continuation of Kotlin Essentials.
This book focuses on Kotlin’s functional features, including:
