Map

A map is a container type that holds key-value pairs, which are mappings from one value to another value. Elements in a map are ordered based on the order of key-value pairs when you create the map, and you access elements in the map using the unique keys you define.

For example, if you want to keep a count of how many times you encounter a word, you can create a map using the word as the key and its count as the value.
