To add elements to an array we will to use the splice function.

.splice(index, howmany, item1, ....., itemX)

index : what position to add/remove items, Use negative values to specify the position from the end of the array
howmany : items to be removed. If set to 0, no items will be removed
item1, ..., itemX Optional. The new item(s) to be added to the array
