Bleep Bleep: SyntaxError, Invalid Shorthand Property intializer


So I'm stuck on 16.5, Bleep Bleep. ([]) This seems to be a tricky exercise for a few of us and I've looked at other posts but the only person I see who has received this SyntaxError, Invalid Shorthand Property Initializer

var cashRegister = {
lastTransactionAmount: 0,
//Dont forget to add your property
add: function(itemCost) { += 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.lastTransactionAmount;


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

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




Have a close look at your property-initialization

voidLastTransaction = function() { -= this.lastTransactionAmount;



Yea, thank you for that.
Been there, tried that. instead of this I used -= cashRegister.lastTransactionAmount , -= add.lastTransactionAmount and even the scan method and plain old total -+ lastTransactionAmount to cover my bases.
So if anyone has anymore direct help than to re-examine the code I've already reviewed multiple times, that would be great.



Try using

voidLastTransaction : function() { -= this.lastTransactionAmount;



wow. Thanks @leonhard.wettengmx.n I did not even think about swapping a colon for the equal signs.
thank you very much!
