Question

Помогите наследованием через extend



function extend(Child, Parent) {
var F = function() { }
F.prototype = Parent.prototype
Child.prototype = new F()
Child.prototype.constructor = Child
Child.superclass = Parent.prototype
}

// создали базовый класс
function Animal(..) { this.one=90 }

// создали класс
// и сделали его потомком базового
function Rabbit(..) { ... }
extend(Rabbit, Animal)

// добавили в класс Rabbit методы и свойства
Rabbit.prototype.run = function(..) { ... }

// все, теперь можно создавать объекты
// класса-потомка и использовать методы класса-родителя
rabbit = new Rabbit(..)
alert(rabbit.one)//ошибка

можно полный пример ?!Очень буду благодарен :dash:
