I get this error: Uncaught ReferenceError: Alireza is not defined . Anybody knows where I made mistake?

var first = {

greet: function (name, mood){
    name = name || "You";
    mood = mood || "good";
    console.log("Hello " + name +
        " I am " + this.name + 
        " and I am in a " + mood + " mood!");


var firstGreet = first.greet; firstGreet.call(Alireza, "red", "blue");

Have you defined the Alireza variable your are passing into your call() statement? The Alireza variable have to be an object.
