Object.setPrototypeOf() — inheritance chain

📖 Usage Example
// Set the prototype of an object
const animal = { breathe() { return true } }
const dog = {}
Object.setPrototypeOf(dog, animal)
dog.breathe()   // → true

Use Object.setPrototypeOf() to dynamically change an object's prototype, though creating objects with the correct prototype upfront is preferred.
