testCallApply.js

function Product(name, price) {
    this.name = name;
    this.price = price;
}

function Food(name, price) {
    Product.call(this, name, price);
    this.category = 'food';
}

function Toy(name, price) {
    Product.call(this, name, price);
    this.category = 'toy';
}

var cheese = new Food('feta', 5);
var fun = new Toy('robot', 40);

console.log(cheese);
console.log(fun);


function f(a,b,c,d){
    console.log(this.x);
    console.log(arguments);
    console.log(a);
    console.log(typeof arguments)
}

var obj = {x:4};
f.call(obj,11,22,33,44,55);
f.apply(obj,[55,44,33,22,11]);
