Is it possible to replace the prototype of an object with a different object?

When an entity is generated, its prototype is established as another entity.

Is it possible to alter the prototype of a previously created entity to point to a different object?

Answer №1

Yes, you have the option to utilize Object.setPrototypeOf(), which comes with some helpful warnings:

const parent = {
    message: "hello"
}

const child = {}
// check object prototype
console.log(Object.getPrototypeOf(child))

Object.setPrototypeOf(child, parent)
// confirm parent as prototype
console.log(Object.getPrototypeOf(child))

// access parent properties
console.log(child.hasOwnProperty('message')) // not part of child object
console.log(child.message)
