What is the difference in performance between iterators and iterables?

What is the difference in performance between iterators and iterables?

Iterators are generally more memory efficient than iterables because they generate items on the fly, while iterables store all items in memory.

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

Sure! Use an iterator when dealing with large datasets where you want to minimize memory usage, like reading a large file line by line.

Are there any performance benchmarks comparing the two?

Yes, benchmarks typically show that iterators can be faster for large datasets due to lower memory overhead, but it depends on the use case.

What about the ease of use? Are iterables easier to work with?

Yes, iterables are often easier to work with since they allow for more straightforward syntax and can be used in loops directly.
