But rufus is created with a new keyword and function Cat(), it should has a constructor property of value Cat(). Actually in my test, when Cat.prototype=new Pet() is commented, rufus exhibits its constructor property as Cat(). Can you explain it more? ‘When you look at the constructor property of the rufus object, rufus doesn’t have a value set explicitly on it so it looks for it on the Cat’s prototype object where it is set to Pet.’
