What is the performance impact of memoization in programming?

Memoization is an optimization technique that can significantly improve the performance of functions by caching results of expensive function calls.

Can you give me an example of how memoization works?

Sure! For instance, in a Fibonacci sequence calculation, memoization stores previously computed Fibonacci numbers to avoid redundant calculations.

Are there any downsides to using memoization?

Yes, while memoization can speed up performance, it can also increase memory usage due to storing cached results.

When should I consider using memoization?

Consider using memoization when dealing with recursive functions or expensive computations that are called multiple times.
