Console: ReferenceError: applyStaffDiscount is not defined
Popup window: 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("me",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;

    },
    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));

what is wrong. I am confused


#2

applyStaffDiscount is a method of cashRegister class, just like scan, so you need cashRegister.applyStaffDiscount() just like you did cashRegister.scan()

given the methods are part of the class, you need to specify the class
