Why doesn’t deleting from a Javascript array change its length?

Question

I have an array:

data.Dealer.car[0]
data.Dealer.car[1]
data.Dealer.car[2]

If I do this:

alert(data.Dealer.car.length);
dele         


        

Answer 1

Array.shift() would remove the first item from the array and make it shorter. Array.pop() will remove the last item.
