Changing the prototype of an object on IE

Is it possible to change the prototype of an object in IE? Chrome and Firefox support the __proto__ attribute for this, but IE doesn't.

Have you considered just setting the prototype like so:

function Vehicle(tires) {
    this.tires = tires;
}

function Car(doors) {
    this.doors = doors;
}

Car.prototype = new Vehicle(4);

function Coupe(seats) {
    this.seats = seats
}

Coupe.prototype = new Car(2);

JavaScript does not allow the prototype of an object to be changed. __proto__ is not a standard property and you should not rely on it.

In general you should use getProtoTypeOf to get the prototype of an object.
