You Deserved It!


After a couple of attempts, I got the right code (pasted below). But my errors were because I had typed in cashRegister.applyStaffDiscount('me') instead of cashRegister.applyStaffDiscount(me). Why is the former code incorrect?

function StaffMember(name,discountPercent){ = 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 = {
    lastTransactionAmount: 0,
    add: function(itemCost){ += (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.lastTransactionAmount;
        this.lastTransactionAmount = 0;
    // Create a new method applyStaffDiscount here
    applyStaffDiscount: function(employee) { = (100-employee.discountPercent)/100*;

// Apply your staff discount by passing the 'me' object 
// to applyStaffDiscount

// Show the total bill
console.log('Your bill is ';


When you put quotation marks around text, it turns the text into a string. When you type me with the quation marks you selected the variable me rather than a string says 'me'.


Thanks for the quick clarification :slight_smile:


hey why do you use

over what they say to use???? -= * (employee.discountPercent / 100);
thanks in advance
