Question

What is the difference between an Iterator and a Generator?

Answer 1

An iterator is commonly used to move through a collection of items. Often having MoveNext() and Current() methods. MoveNext() would shift the pointer to the next collection item (if possible) and return true/false based on success. Current() would provide the actual value.

A generator is an implementation of iterator, but instead of pointing to a pre-existing collection, it creates new items on each MoveNext() call.
