Array Splice Method also alters the original array

Array splice method will alter the actual array. Usually I use the splice approach as in most cases the original array is not required but in case that is required you can create a copy of original Array using

const clonedArray = JSON.Parse(JSON.stringify(array));

and then apply splice on clonedArray like

const firstEightArrayKeys = clonedArray.splice(0,8);
