Convert object to a Map - JavaScript

Suppose we have an object like this −

const obj = {
   name: "Vikas",
   age: 45,
   occupation: "Frontend Developer",
   address: "Tilak Nagar, New Delhi",
   experience: 23,
 };

We are required to write a JavaScript function that takes in such an object with key value pairs and converts it into a Map.

Example

Let's write the code for this −

const obj = {
   name: "Vikas",
   age: 45,
   occupation: "Frontend Developer",
   address: "Tilak Nagar, New Delhi",
   experience: 23,
   salary: "98000"
};
const objectToMap = obj => {
   const keys = Object.keys(obj);
   const map = new Map();
   for(let i = 0; i < keys.length; i++){
      //inserting new key value pair inside map
      map.set(keys[i], obj[keys[i]]);
   };
   return map;
};
console.log(objectToMap(obj));

Output

The output in the console: −

Map(6) {
   'name' => 'Vikas',
   'age' => 45,
   'occupation' => 'Frontend Developer',
   'address' => 'Tilak Nagar, New Delhi',
   'experience' => 23,
   'salary' => '98000'
}
