# Что выведет instanceof?
В коде ниже создаётся простейшая иерархия классов: `Animal -> Rabbit`.
Что выведет [instanceof](/instanceof)?
Распознает ли он `rabbit` как `Animal`, `Rabbit` и к тому же `Object`?
```js
function Animal() {}
function Rabbit() {}
Rabbit.prototype = Object.create(Animal.prototype);
var rabbit = new Rabbit();
alert( rabbit instanceof Rabbit );
alert( rabbit instanceof Animal );
alert( rabbit instanceof Object );
```
