javascript print output in reverse order

Question

<script language=javascript type="text/javascript">  
            for (i=0;i < 10; i++) {
      document.write(i);
     }  
</script>

How can I print the output of this code which is 0123456789 backwards?

read the documentation before asking.. `for (i=10;i > 0; i--)` — Hardy, Aug 06 '16 at 22:15

just set index as highest value, then run it to -1, javascript will automaticly break it at 0.

for (var i=9; i > -1; i-=1) {
      box.innerHTML += i+" <br/>";
}

<div id="box"></div>

Edit: Reasons to use a html element and write to that instead of using document.write can be found here: Why is document.write considered a "bad practice"?

What does div's and boxes have to do with this question? Don't think that was part of the question. – Charlie Fish Aug 06 '16 at 22:42
@CharlieFish I really don't care tbh, i will not support the use of document.write.. – user2267175 Aug 06 '16 at 22:46
That would be a great thing to include in your answer. Why you didn't use `document.write` and why your solution is better would be great things to put in answers. :) – Charlie Fish Aug 06 '16 at 22:49
Valid point i suppose, adding a link to another post explaining it in details :) – user2267175 Aug 06 '16 at 22:50
Also remember the question asks it to print from 9 to 0. Your code currently prints 10 to 0. – Charlie Fish Aug 06 '16 at 22:54
fine.. my faith in humanity just dropped a bit if it's really come to the point where someone can't change a 10 to a 9 by themselves haha :P – user2267175 Aug 06 '16 at 22:58
