Question

How do you define property on Object constructor?

Answer 1

The Object.defineProperty() static method is used to define a new property directly on an object, or modify an existing property on an object, and returns the object. Let's see an example to know how to define property,

const newObject = {};

Object.defineProperty(newObject, "newProperty", {
  value: 100,
  writable: false,
});

console.log(newObject.newProperty); // 100

newObject.newProperty = 200; // It throws an error in strict mode due to writable setting
