Preface

Design patterns represent a compendium of best practices and replicable solutions for frequently encountered software development challenges. These patterns, forged through the collective experience of seasoned developers, offer proven solutions for specific, recurring issues in software design, adaptable to a range of situations. They furnish developers with a shared vocabulary to facilitate communication, collaboration, and code maintenance. Fundamentally, design patterns empower developers to write superior, more efficient, and maintainable code by diminishing the time spent devising solutions for common problems from the ground up.

Kotlin is a versatile programming language that embraces multiple programming paradigms and was crafted by JetBrains, who are renowned for creating widely-used integrated development environments, including IntelliJ IDEA.

The primary goal of this book is to introduce you to classical design patterns, whether you’re unfamiliar with them entirely or are seeking to implement them in Kotlin after using them with other languages. Kotlin, a contemporary language, naturally integrates many essential design patterns within its own syntax and core libraries, often eliminating the need to implement these patterns manually. Nonetheless, recognizing the design patterns embodied by specific language features remains valuable.

This updated edition focuses on the advancements in Kotlin up to Kotlin 2.0. With the ongoing evolution of the Kotlin ecosystem, this edition highlights some of the most thrilling features, such as context receivers, and significant libraries like Arrow, justifying the need for this new edition.
