how use javascript

reverse array

i wanted it is("861", "860","859","858" ............. )

    var arr = [
                "803", "812", "828", "846", "851",
                "852", "853", "857", "858", "859", "860", "861"
               ];
    var splitarr = arr.split(",");
     for (var i = 0; i < arr.length; i++){
        console.log(splitarr);
     }

it is java arrays?

arr is an Array. Arrays don't have a .split() method. Also: RTFM. — George

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);

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()
