How to create an Empty Map in JavaScript - Step by Step Examples

How to create an Empty Map in JavaScript ?

To create an empty map in JavaScript, you can use the Map constructor. This creates a new, empty Map object.

We can create an empty map in JavaScript using the Map constructor, which initializes a map with no key-value pairs.

For example,

We start by declaring a variable named emptyMap. This variable will hold our empty map.
We then use the new Map() constructor to create a new, empty Map object. In JavaScript, the Map constructor initializes the map with no key-value pairs.
The newly created map is now assigned to the emptyMap variable. In this example, the map has string keys and number values.
We can now perform various operations on this empty map, such as adding key-value pairs, checking for the presence of keys, and retrieving values.

let emptyMap = new Map();

// Operations on the empty map
// ...

console.log(emptyMap);

Map(0) {}
