What are performance decorators in programming?

Performance decorators are special functions that modify the behavior of other functions to enhance their performance.

Can you give me an example of how to use a performance decorator?

Sure! Here's a simple example in Python that caches results to improve performance:

def cache(func):
    results = {}
    def wrapper(*args):
        if args not in results:
            results[args] = func(*args)
        return results[args]
    return wrapper

@cache
def slow_function(x):
    # Simulate a slow computation
    return x * x

What are the benefits of using performance decorators?

They can significantly reduce execution time, especially for expensive function calls, by avoiding redundant calculations.

Are there any downsides to using decorators?

Yes, they can add complexity to your code and may introduce overhead if not used judiciously.
