Question

How do you create an object with prototype?

Answer 1

The Object.create() method is used to create a new object with the specified prototype object and properties. i.e, It uses an existing object as the prototype of the newly created object. It returns a new object with the specified prototype object and properties.

const user = {
  name: "John",
  printInfo: function () {
    console.log(`My name is ${this.name}.`);
  },
};

const admin = Object.create(user);

admin.name = "Nick"; // Remember that "name" is a property set on "admin" but not on "user" object

admin.printInfo(); // My name is Nick
