Welcome back, future JavaScript master! Our mission is to master JavaScript Maps, a tool for managing data using key-value pairs that distinguish them from objects (dictionaries). Buckle up; we're about to dive deep into data management using maps in JavaScript!

A Map in JavaScript is a guide to the treasures of unique key-value pairs. Unlike JavaScript objects, which mostly use strings as keys, Map permits any type of keys, thus charting a unique path to each treasure.

Here is an example of creating and populating a Map:
