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

If you want to remove an item, use the splice method:

alert(data.Dealer.car.length);
data.Dealer.car.splice(1, 1);
alert(data.Dealer.car.length);

But notice that the indices have changed.
