Tell us what’s happening:
How do we indicate in the code that ANIMAL is the supertype (parent) of DOG and BIRD? I can’t see this relationship.

Your code so far


function Cat(name) {
this.name = name;
}

Cat.prototype = {
constructor: Cat
};

function Bear(name) {
this.name = name;
}

Bear.prototype = {
constructor: Bear
};

function Animal() { }

Animal.prototype = {
constructor: Animal,
eat: function(){
  console.log("nom nom nom");
}
};
