Javascript Object.create()

The Object.create() method creates a new object using the prototype of the given object.


let Student = {
  name: "Lisa",
  age: 24,
  marks: 78.9,
  display() {

// create object from Student prototype let std1 = Object.create(Student); = "Sheeran"; std1.display(); // Output: Name: Sheeran

create() Syntax

The syntax of the create() method is:

Object.create(proto, propertiesObject)

The create() method, being a static method, is called using the Object class name.

create() Parameters

The create() method takes in:

  • proto - The object which should be the prototype of the newly-created object.
  • propertiesObject (optional) - An object whose enumerable own properties specify property descriptors to be added to the newly-created object. These properties correspond to the second argument of Object.defineProperties().

create() Return Value

  • Returns a new object with the specified prototype object and properties.

Note: If proto is not null or an Object, TypeError is thrown.

Example: Using Object.create()

let Animal = {
  isHuman: false,
  sound: "Unspecified",
  makeSound() {

// create object from Animal prototype let snake = Object.create(Animal);
snake.makeSound(); // Unspecified // properties can be created and overridden snake.sound = "Hiss"; snake.makeSound(); // Hiss // can also directly initialize object properties with second argument let properties = { isHuman: { value: true, }, name: { value: "Jack", enumerable: true, writable: true, }, introduce: { value: function () { console.log(`Hey! I am ${}.`); }, }, };
human = Object.create(Animal, properties);
human.introduce(); // Hey! I am Jack.


Hey! I am Jack.
