Well, I can remove items from the beginning and the end of my array, but If I want to remove the item in the middle?

var number = [1, 2, 3, 4] I want to remove number[2] but keep the rest, what should I do?

var indexToRemove= array.indexOf(2); -> this returns the index of number 2 Then remove it with splice: if (indexToRemove > -1) { array.splice(indexToRemove, 1); }

second param refers to the amount of elements you want to remove.
