What are some common errors when using the decorator pattern?

What are some common errors when using the decorator pattern?

Some common errors include not properly chaining decorators, forgetting to call the wrapped function, and using decorators that alter the function signature.

Can you explain what it means to chain decorators?

Chaining decorators means applying multiple decorators to a single function, where each decorator wraps the previous one, allowing for layered functionality.

What happens if I forget to call the wrapped function?

If you forget to call the wrapped function, the original functionality will not execute, leading to unexpected behavior or results.

Are there best practices to avoid these errors?

Yes, best practices include clearly defining the purpose of each decorator, testing them individually, and ensuring proper function signatures are maintained.
