Design Patterns: Elements of Reusable Object-Oriented Software

Design patterns are proven solutions to common problems faced when designing software systems using object-oriented principles. They provide a template or blueprint for how to organize code effectively, ensuring it's flexible, reusable, and easier to maintain. By recognizing recurring scenarios, developers can apply these patterns to solve issues efficiently without reinventing the wheel. Think of design patterns as best practices or proven strategies that guide the structure and interaction of code components, leading to more reliable and understandable software architecture.
