✅ Topic : What is Map in JavaScript ?

"new Map()" - is a built-in object in JavaScript that represents a collection of key-value pairs. It was introduced in ECMAScript 6 and is similar to an object, but with some important differences.

One of the main differences between a Map object and a regular JavaScript object is that the keys in a Map object can be any type of value, including objects and functions, while the keys in an object must be strings or symbols.
