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')
}
})
