Answer
It provides a flexible alternative to adding new behaviors.
The Decorator pattern allows you to add functionality at runtime without creating a potentially large hierarchy of subclasses. This keeps the class model simple and more adaptable to changes, as behaviors can be added or removed as needed. For instance, a base Product class can have multiple decorators for different pricing strategies like discounts or taxes without subclassing.
