Answer
By wrapping the object with a new class that adds additional behavior.
The Decorator Pattern allows you to add new functionality to an object dynamically by wrapping it in a new class called a decorator. This decorator class implements the same interface as the original object, allowing you to extend its behavior without modifying the object's code. For instance, in an e-commerce platform, you can create a 'DiscountDecorator' to add a holiday discount to the base price of a product. This approach prevents the need for a multitude of subclasses and keeps the system flexible and easy to modify.
