Cant you just pop out a number like that without having to use the shift method

But you could get rid of the 2 using "splice":
number.splice(1, 1);

230,995 PointsThe "pop" method doesn't take an argument (it will ignore any given).
While "shift" removes the first item from an array, "pop" removes the last item from the array.

4,503 PointsThank you but I have one more question. In this quiz what is the answer to the question that asks to store the numbers like 78, 81, 83, and few other numbers : https://teamtreehouse.com/library/javascript-arrays-and-loops/tracking-multiple-items-with-arrays/review-adding-and-removing-items-from-arrays
Steven Parker
230,995 PointsI believe the question you are referring to is asking for the number of items. The number of items in an array can be access by using the length property.
