Answer
By composing behaviors at runtime rather than creating new subclasses for every combination.
Instead of creating many subclasses to represent each feature combination (e.g., different discount types), decorators allow you to add features dynamically. For instance, rather than creating a class for every discount combination, you can create one for each discount type and combine them as needed.
