When should I avoid using memoization?

When should I avoid using memoization?

You should avoid using memoization when the function has side effects, as it can lead to incorrect results.

Can you give me an example of a function with side effects?

Sure! A function that modifies a global variable or interacts with I/O operations, like reading a file, has side effects.

What about memory usage? Does memoization always help?

Not always. If the memoized results consume too much memory or if the function is rarely called, it might be better to avoid it.

Are there any performance trade-offs I should consider?

Yes, memoization can introduce overhead due to storage and retrieval of cached results, which may negate its benefits.
