What are the best practices for using the decorator pattern?

The decorator pattern is great for adding functionality to objects dynamically. Best practices include using it to adhere to the Single Responsibility Principle, ensuring decorators are transparent, and keeping the interface consistent.

Can you give an example of how to implement it?

Sure! For instance, if you have a Coffee class, you can create a MilkDecorator that adds milk functionality without modifying the original class.

What are the advantages of using the decorator pattern?

The main advantages include enhanced flexibility, the ability to add responsibilities at runtime, and promoting code reusability.

Are there any common pitfalls to avoid?

Yes, avoid overusing decorators as it can lead to complex code. Also, ensure that decorators do not alter the core behavior of the object.
