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");
