Class checking: "instanceof" misleading sentence and example.

Great tutorial, thanks so much!
Since the comment section was removed, just wanted to add here a correction. In the parragraph: "It also works with constructor functions:" the example below is not a constructor function. What you are using is precisely an instance of Rabbit, but in the form of "new Rabbit()". It could be misleading to say that the instanceof operator works with constructor functions.

Locate the tutorial section containing the sentence “It also works with constructor functions:” and its `new Rabbit()` example. Read the surrounding explanation of `instanceof`, then correct the misleading wording and example distinction; done means the passage accurately describes what `instanceof` operates on.
