How does the decorator pattern compare to other design patterns?

The decorator pattern allows behavior to be added to individual objects, either statically or dynamically, without affecting other objects. It's often compared to the strategy and observer patterns, which also deal with behavior but in different ways.

Can you explain how the decorator pattern differs from the strategy pattern?

Certainly! The decorator pattern adds responsibilities to objects dynamically, while the strategy pattern defines a family of algorithms and makes them interchangeable. In essence, decorators enhance functionality, whereas strategies change behavior.

What are some real-world examples of the decorator pattern?

Common examples include adding features to a coffee order, like milk or sugar, or enhancing a graphical user interface component with additional functionalities.

Are there any drawbacks to using the decorator pattern?

Yes, one drawback is that it can lead to a complex system of decorators, making it harder to understand the overall structure. Additionally, it may introduce more classes than necessary.
