Question

var x=5
var char="Hi!

Is there any way to make JS write char x amount of times inside of an html element?

<span>Hyper guy wants to tell you 
<script>
var x=5;
var char="Hi!;
document.write(char) and repeat x times;
</script>
</span>

The problem with using document.write is that it erases the whole page, so how would I insert it in context?

Answer 1

Use a loop that loops 5 times, each time adding ‘Hi!’ onto the end.

var x = 5;
var char = '';
while (x--) {
    char += 'Hi!';
}
// write once
document.write(char);

Or, you can just write 5 times:

var x = 5;
var char = 'Hi!';
while (x--) {
    document.write(char);
}

Up to you which you choose, though I’d prefer the first (the less you mess with the document, the better).
