What am i not seeing


#1


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("Myke",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);  //Calculate pecentage total
    },
    
};

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

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


7. You Deserve it!


I keep getting NaN as a result im assuming something is misnamed or my math is off but im not sure how


Replace this line with your code.


#2

here:

cashRegister.applyStaffDiscount("me");

you supply "me" is argument. But a string doesn't have discountPercent property. Supply the me instance as argument

Wow I just spent three days thinking i totally sucked at this and i was the worst coder in the world and the whole time it was a couple quotation marks. Lol Thank you very much i guess i need to get better at the details

Thank you


#4

those quotation marks make a huge difference (string vs variable, in this case the variable is object instance)

Programming really requires attention to detail, it will get better :slight_smile:
