Async Attribute and Scripts At The Bottom

A reader recently wrote in and (essentially) asked me:

Is there any reason to use the async attribute when the script is already at the bottom of the page?

I'm not a master at this stuff, but this is how I understand it...

What he was talking about was this:

<script async src="/js/script.js"></script>

</body>

We've covered this before a bit. It's extra-interesting to re-visit now though, because the async attribute is now really the only recommended way to be doing …
