Right now there is no way to remove an item form array on a specific index.
var fruits = ["Banana", "Orange", "Apple", "Mango"]; fruits.splice(0, 1); // Removes the first element of fruits
The first parameter (0) defines the position where new elements should be added (spliced in).
The second parameter (1) defines how many elements should be removed.
The rest of the parameters are omitted. No new elements will be added.
