<script> async, defer, async defer, module, nomodule, src, inline - the cheat sheet

With the addition of ES modules, there's now no fewer than 24 ways to load your JS code: (inline|not inline) x (defer|no defer) x (async|no async) x (type=text/javascript | type=module | nomodule) -- and each of them is subtly different.

This document is a comparison of various ways the <script> tags in HTML are processed depending on the attributes set.

If you ever wondered when to use inline <script async type="module"> and when <script nomodule defer src="...">, you're in the good place!

Note that this article is about <script>s inserted in the HTML; the behavior of <script>s inserted at runtime is slightly different - see Deep dive into the murky waters of script loading by Jake Archibald (2013)

[I ran across these on a Unix salesman's wall and haven't seen them posted
 before.  I modified them here and there.  Followups are in net.jokes.]
People who come into contact with the Unix system are often told, 
"If you have trouble, see so-and-so, he's a guru", or "Bob there is
a real Unix hacker."

What is a "Unix Wizard"?  How does s/he differ from a "guru"?

To explore these and other questions, here is a draft of the "Unix Hierarchy":
