19.Black (and White) Penguin Magic



I cant see where my mistake is. The error message is 'Oops, try again. Your code threw the following error: TypeError: Right-hand side of 'instanceof' is not callable'

// the original Animal class and sayName method
function Animal(name, numLegs) {
    this.name = name;
    this.numLegs = numLegs;
Animal.prototype.sayName = function() {
    console.log("Hi my name is " + this.name);

// define a Penguin class
function Penguin(name) {
    this.name = name;
    this.numLegs = 2;

// set its prototype to be a new instance of Animal
Penguin.prototype = new Animal();

var Penguin = new Penguin("Muhsin");


this line:

var Penguin = new Penguin("Muhsin");

you can't give the variable the same name as the object, that is a conflict. you could call it penguin, since this is a different name (variable names are case sensitive)
