I realized I haven't posted this here yet, so: Web devs! I launched an online course about Web Components this summer. You can find out about it here on this site, and oh! there's a big discount sale running for a couple of more days. 🙌 scottjehl.com/learn/webcom...

Web Components Demystified online course | Scott Jehl, Web Designer/Developer

A comprehensive, premium course about building dynamic, fast, resilient apps with standard web components.

If you've piece-meal assembled your JS knowledge over the years AND you care more about "how it works" as opposed to "how to npm install my problems away", get this course!!1

I've learned a lot from @wil.to over the years and he'll engage and entertain you the whole way.

At last, today is the day. I am immensely proud to announce that JavaScript for Everyone is here.

Tell a friend, tell a Slack channel — write it on a slip of paper, fold it once, and slide it across your boss' desk without breaking eye contact. _It's time to get weird._

JavaScript for Everyone

A high quality, expansive written course that will elevate your JavaScript skills to a level you never thought was achievable.

Hmm. Need to find my notes :) Needing to wrap brings to mind some limitations with elements that may not be able to be wrapped in their particular DOM location, or because a layout has assumptions about siblings and such already. I think an attribute offers the cleanest means of enhancing an element

I've seen such stances change in standards 🤷‍♂️

Really nice to see "Custom Built-ins" aka the "is" attribute on this list. I've been vocal for a long time about this one being possibly *the* default way I'd use web components if it only worked in webkit/Safari (works everywhere else)

I listed it #1.

My list of priorities with custom elements that extend built-ins at the top!

SVGOMG has been updated to use SVGO 4! (thanks Adrien Crivelli!)

This is the URL for SVGOMG. Unfortunately someone maintains a fork with ads, so, err, don't use that 😀

I may be missing some nuance here but for me, introducing Shadow DOM in general brings all sorts of caveats I often don't want, especially with forms. Having to involve element internals and formAssociated to get form elements recognized in a form is a big jump. I'd prefer extending a usable base.

...although funny enough this one seems to have what it needs to render... unclear why it doesn't until/unless the JS makes it so. Not going to investigate 🤷‍♂️
