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

The decorator pattern is widely used in scenarios where you want to add responsibilities to objects dynamically. For example, in GUI frameworks, you can use decorators to add features like borders or scroll bars to windows.

Can you give me more examples in software development?

Sure! In logging, you can use decorators to add logging functionality to methods without modifying their code. Also, in web development, decorators can be used to add authentication or caching to routes.

How does it compare to other design patterns?

The decorator pattern is more flexible than inheritance because it allows behavior to be added at runtime. Unlike the strategy pattern, which defines a family of algorithms, decorators can wrap any object to enhance its functionality.

Are there any downsides to using the decorator pattern?

Yes, one downside is that it can lead to a complex system of decorators, making it harder to understand the overall behavior of an object. Additionally, excessive use can complicate debugging.
