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");
}

};

Hello there.

Do you have a question?

If so, please edit your post to include it in the Tell us what’s happening section.

Learning to describe problems is hard, but it is an important part of learning how to code.

Also, the more information you give us, the more likely we are to be able to help.

when i would create a cat with the cat constructor, which dont has the function eat in it, it would still be created with the function eat, because its in Animal.prototype, but i dont understand, where does the program know it from, that Animal.prototype is a superttype for cat ?

In the code for that challenge, Bear and Cat aren’t subtypes of Animal yet. How to do that will be covered in the next two inheritance lessons.
