how can I make my assigned array refresh itself if I delete an item javascript code example

Example 1: delete from array javascript

var arr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0];var removed = arr.splice(2,2);/*removed === [3, 4]arr === [1, 2, 5, 6, 7, 8, 9, 0]*/

Example 2: js remove element from array

let arrDeletedItems = array.splice(start[, deleteCount[, item1[, item2[, ...]]]])
