The book 'Design Patterns: Elements of Reusable Object-Oriented Software,' often referred to as the 'Gang of Four' book, is a seminal work in software engineering that introduces and classifies common solutions to recurring design problems in object-oriented programming. It provides detailed descriptions of 23 classic design patterns, such as Singleton, Observer, Factory, and Decorator, along with implementation examples and guidance on when and why to use them. The book aims to promote reusable, maintainable, and scalable software design practices.
Key Features
- Comprehensive catalog of 23 core design patterns in object-oriented software development
- Clear classification into creational, structural, and behavioral patterns
