►Lesson Description: In this lesson I present to you the behavioral pattern for the iterator. Iterating through code is something you are likely familiar with, but using iterators is useful for clearly showing the intent in the code for how you traverse a data structure. Additionally, iterators provide a uniform way to traverse a data structure if you need to make changes in multiple places.
