Supertype/DRY Challenge

Tell us what’s happening:
Describe your issue in detail here.
I was able to pass this challenge so I don’t have any code specific questions but I am not sure I understand how the supertype works. In this example, how does the eat function remain a property of the objects Bear and Cat? In other words, how do the types know that Animal is a supertype?
Your code so far

function Cat(name) { = name;

Cat.prototype = {
constructor: Cat

function Bear(name) { = name;

Bear.prototype = {
constructor: Bear

function Animal() { }

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

Challenge: Use Inheritance So You Don’t Repeat Yourself

Or is this what is explained in the next challenge and we need to have Object.create(Animal.prototype); inside the function?
