SyntaxError: Missing : after property id

I'm pretty sure there isn't a ":" missing, but I've been coding for a while today so maybe I'm missing it...I looked to a handful of Q&A topics on #5 but I haven't been able to figure out what's wrong. Help would be appreciated!


var cashRegister = {
    total: 0,
    lastTransactionAmount: 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
    function voidLastTransaction() {
        this.total -= 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.scan('chocolate',3);


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

Notice anything missing here?


#3

Womp. Exactly why I posted haha, but now it says missing } after property list?


#4

Could you paste your code after you inserted the : ?


#5

The function "voidLastTransaction()" is the last property in your "cashRegister" object, so it doesn't need a comma after the closing curly brace.


#6

var cashRegister = {
total: 0,
lastTransactionAmount: 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
function: voidLastTransaction() {
this.total -= 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.scan('chocolate',3);

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

Switch function and voidLastTransaction.
