See your subject-line:
Re: Reverse elements in array, they can be integers or strings.

So your Q logically is a miswriting of "reverse elements of an array",
but your English is so bad that it now seems you ment
"reversing the content of individual elemnets of an array"

> the digits/characters of the the element, 

Elements of an array do not have digits,
elements of an array do not have characters.

Elements of an array have values of one of the types
floating point numeric, string, array or object. 

> only the order of the element.

and an element has no order.

> There is a difference you know.

A single element is just like any other variable, 
so you could better, much better, have asked:

"how do I reverse the value of a variable?"

Which shows the nonsense of your Q.

> var arrlen = arr.length;
> for (var i=arrlen;;i--) document.write(arr[i-1]+'<br>');

It is not at all useless, 
maybe you should ask that of yourself, 
when you ask improperly constructed Qs. 

If the content of an element of your array
has the value of an array in itself,
yes then it is possible to invert that array,
and even then it is wasting processor-time to do so,
when printing printing, 
as the above function can be rewritten to:

var i, j;
for (j=arr.length;;j--) {
  for (i=arr[j].length;;i--) 
    document.write(arr[j-1][i-1]+';'); 
  document.write('<br>');
};
