javascript remove values from (inside) object literal

Question

I'm trying to remove an object from (inside?) a object literal. But I cant figure out why it doenst work.

var data= 
{
   "car": 3,
   "boat": 2
};

data.pop(); //should remove last one?
data.splice(1, 1); // removes element with index 1?

What am I doing wrong here? And is it posible you delete the item by name? Let say remove boat.

Answer 1

Since its a Object not an array, delete should work

Like this:

var data= 
{
   "car": 3,
   "boat": 2
};

alert(data["boat"]);
delete data["boat"];
alert(data["boat"]);
