What are decorator parameters in programming?

Decorator parameters are arguments passed to decorators, allowing customization of their behavior.

Can you give me an example of a decorator with parameters?

Sure! Here's a simple example in Python:

def my_decorator(param):
    def wrapper(func):
        def inner(*args, **kwargs):
            print(f'Parameter: {param}')
            return func(*args, **kwargs)
        return inner
    return wrapper

@my_decorator('Hello')
def greet(name):
    print(f'Greetings, {name}!')

greet('Alice')

What happens if I don't use parameters in a decorator?

If you don't use parameters, the decorator will apply the same behavior to every function it decorates, without customization.

Are there any performance implications of using decorators with parameters?

Yes, using decorators with parameters can introduce slight overhead due to the additional function calls, but it's usually negligible.
