Hi I'm trying to display a string vertically, like this:
h
i
t
h
e
r
e

Here's my code, been messing around with it for awhile and can't figure out how to do it right.

var i = 0;
var userString = prompt("Enter a string");

while (userString.length > 0)
{
i++;
document.write(userString(i) + "<br>");
}

You're close, but you have one little error in your code. You are referencing your string length in the while loop and checking if it is > 0. This never changes so you will end up with an infinite loop. What you need to do is reference the variable that is being changed like this:

That does'nt seem to work. Nothing is displaying after user prompt. I'm getting an error in firefox javascript console saying that "userString is not a function" and it highlights "document.write(userString(i) + "<br/>");

edit* I found the problem. I just needed to change userString(i) to
userSrting[i].

Thanks for your help.
