"Kotlin Essentials"
Kotlin Essentials is a comprehensive guide designed to take developers from foundational understanding to expert proficiency in Kotlin, whether they are transitioning from Java, embracing multiplatform projects, or seeking to master advanced language features. The book opens with an in-depth exploration of modern language fundamentals, highlighting Kotlin's expressive syntax, robust static typing with type inference, and innovative null-safety mechanisms. Readers will gain practical insights into control flow, concise function definitions, and the power of extension functions, all compared thoughtfully with Java and Scala paradigms for clear context.
As the journey unfolds, the book delves into the core of Kotlin's object-oriented and functional programming capabilities. It covers advanced class structures, inheritance, abstraction, and the effective use of data, sealed, and singleton objects. Readers will discover patterns for designing extensible hierarchies, building reusable components through delegation and composition, and leveraging powerful functional constructs such as higher-order functions, immutability, and algebraic data types. The advanced type system receives thorough attention, with coverage of generics, variance, inline and reified types, and runtime reflection—ensuring robust, type-safe abstractions for any scenario.
Recognizing the realities of modern software development, Kotlin Essentials expertly addresses asynchronous programming with coroutines, architectural patterns for concurrency, and multiplatform strategies for code sharing across JVM, JS, and Native targets. It guides professionals through effective collection usage, interop with Java and JavaScript, building expressive DSLs, compiling and profiling for performance, and best practices in testing, deployment, and scaling. Whether developing Android apps, server-side systems, or cutting-edge multiplatform solutions, this book provides a complete and authoritative resource for mastering Kotlin in production settings.
