Introduction to Design Patterns
Design patterns are proven solutions to common design problems in software development. Understanding and applying patterns ensures maintainable, scalable, and well-structured code. Mobile development has unique patterns and adaptations of classic patterns for mobile-specific challenges.
Design patterns include: architectural patterns (MVC, MVVM, MVP, Clean Architecture), creational patterns (Singleton, Factory, Builder), behavioral patterns (Observer, Strategy, Command), and structural patterns (Adapter, Facade, Decorator). Understanding when and how to use patterns is critically important.
