How to Create an Empty Map in JavaScript ?

In JavaScript, you can create an empty Map using the Map constructor. whenever we initialize any map it is empty at first and we need to declare the key-value pair inside the map constructor to construct the map having values.

Syntax:

let emptyMap = new Map();

Example: Here, initialMap is a Map that has been initialized with key-value pairs.

let initialMap = new Map([
  ['key1', 'value1'],
  ['key2', 'value2'],
  // more key-value pairs if needed
]);
