Decorator Pattern
The Decorator pattern attaches additional responsibilities to an object dynamically, providing a flexible alternative to subclassing for extending functionality.
The Decorator pattern allows behavior to be added to individual objects, either statically or dynamically, without affecting the behavior of other objects from the same class. This pattern is widely used in React through Higher-Order Components (HOCs) and in Angular through decorators, enabling code reuse and separation of concerns [citation:1][citation:7].
