Oops, try again. It looks like you have an error in your code! Check the error message for more details: ReferenceError: applyStaffDiscount is not defined


function StaffMember(name,discountPercent){
    this.name = name;
    this.discountPercent = discountPercent;
}

var sally = new StaffMember("Sally",5);
var bob = new StaffMember("Bob",10);

// Create yourself again as 'me' with a staff discount of 20%
var me = new StaffMember("Nikhil",20);

var cashRegister = {
    total:0,
    lastTransactionAmount: 0,
    add: function(itemCost){
        this.total += (itemCost || 0);
        this.lastTransactionAmount = itemCost;
    },
    scan: function(item,quantity){
        switch (item){
        case "eggs": this.add(0.98 * quantity); break;
        case "milk": this.add(1.23 * quantity); break;
        case "magazine": this.add(4.99 * quantity); break;
        case "chocolate": this.add(0.45 * quantity); break;
        }
        return true;
    },
    voidLastTransaction : function(){
        this.total -= this.lastTransactionAmount;
        this.lastTransactionAmount = 0;
    },
    // Create a new method applyStaffDiscount here
    applyStaffDiscount: function (employee) {
    this.total -= this.total * (employee.discountPercent / 100)}
    
};

cashRegister.scan('eggs',1);
cashRegister.scan('milk',1);
cashRegister.scan('magazine',3);
// Apply your staff discount by passing the 'me' object 
// to applyStaffDiscount
applyStaffDiscount(me);

// Show the total bill
console.log('Your bill is '+cashRegister.total.toFixed(2));

applyStaffDiscount is a method, part of the cashRegister object, agree? just like scan is a method of the cashRegister object, when you call scan:

cashRegister.scan('eggs',1);

you specify that the method is defined in the cashRegister object, why not do the same for applyStaffDiscount while they are both method of the cashRegister object?


#3

Still kind of lost mate


#4

you can't call a method, without defining the object the method belongs to.

applyStaffDiscount is also a method, you should do objectname.method() to call the method, the objectname is missing when you tr to call applyStaffDiscount


#5

Well that was a bummer..lol Thanks Again! I thought i completely messed up somewhere.
Quick question could you explain what the method actually does?


#6

Never mind I understand it now...Thanks Again though!


#7

in programmin screwing up a bit is enough to get an error.

that depends what is in the method, you can write your ow methods. Methods is just the word used for a function which is part of an object


#8

Yeah both good and bad. It still is exciting when you code and in the end everything works perfectly fine...!


#9

yes, totally agree. The feeling that you made it work is really great :slight_smile: also great to hear you got your code to work :slight_smile:
