The Object setPrototypeOf() method
New Course Coming Soon:
Get Really Good at Git
Find out all about the JavaScript setPrototypeOf() method of the Object object
Set the prototype of an object.
While you’re here, see my guide on JavaScript Prototypal Inheritance
Accepts two arguments: the object and the prototype.
Usage:
Object.setPrototypeOf(object, prototype)
Example:
const Animal = {}
Animal.isAnimal = true
const Mammal = Object.create(Animal)
Mammal.isMammal = true
console.log('-------')
Mammal.isAnimal //true
const dog = Object.create(Animal)
dog.isAnimal //true
console.log(dog.isMammal) //undefined
Object.setPrototypeOf(dog, Mammal)
console.log(dog.isAnimal) //true
console.log(dog.isMammal) //true
