This book starts with core syntax and control flow, then covers variables, data types, and constructs such as if-else, when, while, and do-while loops. It then introduces function design with reusable code, higher-order functions, and lambda expressions. The subsequent chapters thoroughly explore classes and constructors, inheritance, interfaces, and encapsulation principles that promote modular design and data safety. The book devotes a dedicated section to examining collection frameworks, including lists, arrays, sets, and maps, and clearly illustrates filtering, transformation, and iteration techniques. You will learn how immutable snapshots and mutable services interact via observer patterns to synchronize application components in real time. You will learn all about creating a pipeline using chaining, mapping, and flattening operations. Finally, robust error handling and type-casting strategies provide guidance on exception capture, safe casting, and graceful recovery. Later chapters discuss JSON serialization, RESTful API design, and building a web server with Ktor.
