Answer 1

Simply: reverse()

The reverse() method reverses an array in place. The first array element becomes the last and the last becomes the first.

var arr = [
                "803", "812", "828", "846", "851",
                "852", "853", "857", "858", "859", "860", "861"
               ];
arr.reverse();
console.log(arr);

Answer 2

Array has a reverse function on it's prototype.

var arr = [
                "803", "812", "828", "846", "851",
                "852", "853", "857", "858", "859", "860", "861"
               ];
arr.reverse()
