I use the ` char for multi lines in JS (especially with document.write) which is very useful.
ex:
<script>
document.write(`hello 
    world
    line2
`);
</script>
However I don't really understand what it stands for (and worse) it does not work at all in IE9-IE10-IE11.
Is there a clean alternative to write document.write multi line ?
(I loved that method to avoid using extra chars like \ or having to write document.write for each line until I realized it fails on Internet Explorer)
