This book is designed to serve as an authoritative and comprehensive introduction to the D Programming Language for new readers. It combines safety, control, productivity, and modeling while providing efficient programming standards from the bottom to the highest level. With its C-like syntax and static typing, each chapter builds upon the content of the previous one and introduces as few new concepts as possible. While written with beginners in mind, it covers almost all aspects of the language such as expressions, statements, types, functions, contracts, and modules. It is recommended to read this book linearly, without skipping chapters if possible. Readers will find in-depth explanations with idiomatic examples for all language features, feature groups, and main programming paradigms. Additionally, it provides best-use advice for each major feature and discusses cross-cutting issues such as error handling, contract programming, and concurrency. Tables, figures, and “cheat sheets” serve as an accessible quick reference for everyday problem solving with D. This book is perfect for those seeking an enjoyable yet precise learning experience.
