Javascript Calculator is not passing test number 11

Hi. Your confirmationDot function is only checking if the last item of the array is a dot(.) not if there is a dot(.) in any index of the array, that leaves it open to do something like 6.7.8. You will need the function to check the entire array and only allow one dot(.). Hope this helps.
