What is Map?

A Map is a collection that holds key-value pairs. Think of it like a dictionary where each key is associated with a specific value. Keys are unique within a map, and you use a key to quickly retrieve its corresponding value. Maps are useful for storing and accessing data based on a unique identifier.
