Map object
The Map object is a collection of key-value pairs where each key can be of any type, and each value can also be of any type.
A Map maintains the order of key-value pairs as they were inserted.
// Creating a Map to store person details
const personDetails = new Map ();
personDetails.set("name", "Alice");
personDetails.set ("age", 30);
console. log(personDetails.get ("name"));
// Output: "Alice"
console. log(personDetails.has ("age"));
// Output: true
personDetails.delete("age");
console. log(personDetails.size);
