What are the performance differences between iterables and iterators?

What are the performance differences between iterables and iterators?

Iterables can be traversed multiple times, while iterators can only be traversed once. This affects performance based on use case.

Can you give an example of when to use an iterator over an iterable?

Sure! Use an iterator when you need to process a large dataset without storing it all in memory, like reading a file line by line.

Are there any performance benchmarks comparing the two?

Yes, generally, iterators can be more memory efficient, but iterables may perform better for smaller datasets due to their reusability.

What about the impact on readability and maintainability?

Iterables often lead to clearer code since they can be reused, while iterators can make code more complex but are efficient for large data.
