A demonstration of Ruby closures by Paul Cantrell

# I recommend executing this file, then reading it alongside its output.

# Alteratively, you can give yourself a sort of Ruby test by deleting all the comments,
# then trying to guess the output of the code!
# A closure is a block of code which meets three criteria:

async scripts, defer scripts, module scripts: explainer, comparison, and gotchas

<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)

Created August 23, 2019 14:41 — forked from Starefossen/tmux-cheats.md
My personal tmux cheat sheet for working with sessions, windows, and panes. `NB` I have remapped the command prefix to `ctrl` + `a`.

Sessions

New Session

  • tmux new [-s name] [cmd] (:new) - new session

Switch Session

  • tmux ls (:ls) - list sessions
  • tmux switch [-t name] (:switch) - switches to an existing session
