Question


To convert a JavaScript object to key value, you need to use Object.entries() along with map(). Following is the code −

Example

var studentObject={
   101: "John",
   102: "David",
   103: "Bob"
}
var studentDetails = Object.assign({}, studentObject)
studentDetails = Object.entries(studentObject).map(([studentId,studentName])=>({studentId ,studentName}));
console.log(studentDetails);

To run the above program, you need to use the following command −

node fileName.js.

Here, my file name is demo113.js.

Output

This will produce the following output −

PS C:\Users\Amit\JavaScript-code> node demo113.js
[
   { studentId: '101', studentName: 'John' },
   { studentId: '102', studentName: 'David' },
   { studentId: '103', studentName: 'Bob' }
]
