Hello Friend,

Try this:

<html>
<Script>
var arrsize=window.prompt("Enter size of array: ");
var arr=new Array
for(var i=0;i<arrsize;i++){
var j=i+1;
var element=window.prompt("Enter element "+j);
arr[i]=element;
}
document.writeln("<b>Array Elements</b><br>"); 
for(var i=0;i<arr.length;i++){
document.writeln(arr[i]);
}
document.writeln("<br>");
document.writeln("<b>Array Reverse</b><br>"); 
for(var i=arr.length-1;i>=0;i--){
document.writeln(arr[i]);
}
</script>

</html>
