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

I think you're looking for this:

var arr = [0,1,2,3,4];

alert( arr.splice( 2, 1 ) ); // alerts 2, the element you're removing
alert( arr ) // alerts 0,1,3,4  - the remaining elements
