Summary: iterator in Brief
An 'iterator' [ˈɪtəreɪtə(r)] is a tool used in computer programming to traverse through all the elements of a collection. It allows a programmer to access each element of an array, and is commonly used in object-oriented programming. The 'iterator protocol' is a standard way for objects to be iterable, while the 'iterator design pattern' provides a way to access the elements of an aggregate object sequentially without exposing its underlying representation. A 'lazy iterator' generates the next value only when it is needed.
