Composition Over Inheritance
Prefer composition (has-a) over inheritance (is-a). Inheritance creates tight coupling and fragile base class problems. Compose objects from smaller, focused pieces. Use interfaces to define contracts. JavaScript/TypeScript mixins or object composition enable flexible code reuse without deep hierarchies. Reserve inheritance for true "is-a" relationships with shared behavior.
