Javascript add property to Object

Comment

//JavaScript example code to demonstrate the use of Object.defineProperty() method
let obj = {}; //empty JavaScript object obj
Object.defineProperty(obj, 'id', { //using Object.defineProperty() method of JavaScript object class 
  value: 101,
  writable: false //configured writable property as false, and hence, the id property of object obj can't be changed now
});
obj.id = 412; //no effect on 'id' property
console.log("Object ID:",obj.id); //prints 101

Object.defineProperty(obj, 'name', { //using Object.defineProperty() method of JavaScript object class 
  value: 'Mayank',
  writable: true //configured writable property as true, and hence, the name property of object obj can be changed now
});
obj.name = 'Mayank Jain'; //modifying the name property of object obj (writable property is set to true)
console.log("Object Name:",obj.name); //prints 'Mayank Jain'
