The Object create() method

Find out all about the JavaScript create() method of the Object object

Introduced in ES5.

Creates a new object, with the specified prototype.

Usage:

const newObject = Object.create(prototype)

Example:

const animal = {}
const dog = Object.create(animal)

The newly create object will inherit all the prototyope object properties.

You can specify a second parameter to add new properties to the object, that the prototype lacked:

const newObject = Object.create(prototype, newProperties)

where newProperties is an object of objects that define each property.

Example:

const animal = {}
const dog = Object.create(animal, {
  breed: {
    value: 'Siberian Husky'
  }
});
console.log(dog.breed) //'Siberian Husky'

I didn’t just say breed: 'Siberian Husky' but I had to pass a property descriptor object, defined at the beginning of this page.

Object.create() is often used in combination with Object.assign():

const dog = Object.assign(Object.create(animal), {
  bark() {
    console.log('bark')
  }
})
