Question

Im trying to get my head around javascript inheritance and this code doesnt work cant see why:

function Animal(){

  this.hasfur = true;

}

function Cat(){

  this.sound = "Meow";

}

$(document).ready(function(){

   Cat.protptype = new Animal();

  var myCat = new Cat();

  console.log(myCat.hasfur);


}

The console comes out with undefined. But I thought that when I access myCat.hasfur it should look at the prototype of cat which is vehicle and then look at that property…?

Answer 1

Read that again:

Cat.protptype

I’m pretty sure you meant:

Cat.prototype
