Iterable Interface

An Iterable interface is a way for a data structure, like a list or collection, to allow you to go through its elements one by one. Think of it as a blueprint that enables objects to be looped over seamlessly, such as using a 'for each' loop. It provides a standard method to get an iterator, which manages the process of accessing each item in sequence without exposing the internal details. This makes code more consistent and easier to work with when dealing with various collections of items.
