3. Short-Term-Memory Troubles


#1


I´d appreciate some help on this one, can´t figure it out for myself.
Thanks in advance! :slight_smile:


Reference error: item is not defined

var cashRegister = {
    total: 0,
//insert the add method here    
 add: function(itemCost) {
     this.total += itemCost;
 },

    
    scan: function (itemCost) {
        switch (item) { 
        case "eggs": 
            this.add(0.98); 
            break;
        
        case "milk": 
            this.add(1.23); 
            break;
        
        //Add other 2 items here
        case "magazine":
            this.add(4.99);
            break;
        case "chocolate":
            this.add(0.45);
            break;
        
        }
        return true;
    
}
}

//Scan 2 eggs and 3 magazines
cashRegister.scan("eggs");
cashRegister.scan("eggs");
cashRegister.scan("magazine");
cashRegister.scan("magazine");
cashRegister.scan("magazine");


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

#2

here:

scan: function (itemCost)

why did you change the parameter of scan to itemCost?

Your add method should have a parameter if itemCost, i don't see why you changed the parameter for scan method
