Oops. Try again. False
Console logs Your bill is 7.2chocolate. :confused:

var cashRegister = {
    total:0,
    //Dont forget to add your property
    add: function(itemCost) {
        this.total +=  itemCost;
        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;
    },
    //Add the voidLastTransaction Method here
    voidLastTransaction: function() {
        this.total -= this.lastTransactionAmount;
    }
};

cashRegister.scan("eggs",1);
cashRegister.scan("milk",1);
cashRegister.scan("magazine",1);
cashRegister.scan("chocolate",4);

//Void the last transaction and then add 3 instead
cashRegister.voidLastTransaction();
cashRegister.add("chocolate",3);

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