Said time is, of course, the week of Black Friday — about which I have some Big Feelings: wil.to/newsletters/...
So, if you’re in a position where you’re able to do so, help me make sure JavaScript for Everyone lives up to its name by paying a little more for it.

Not sure how I missed that HTML details elements can act as an accordion now, but they can. developer.mozilla.org/en-US/blog/h...
Exclusive accordions using the HTML details element | MDN Blog
The 'name' attribute of the HTML details element is gaining more support across browsers. Learn how this feature allows creating exclusive accordions without scripting widgets from scratch.

Web devs, metrics are great, but we should be vibe-testing our websites too. Silly term; not sorry! A popular, budget-level Android smartphone is a dev tool. Tether it to a realistic network connection by sharing a hotspot using Charles Proxy and browse away. Keep tabs on the qualitative experience.

I’m honored that @kevinpowell.co invited me on to build a #webcomponent for him and have him implement it and talk about it. I had a great time and hope we can do it again in the future!

Web Components! This post by @zachleat.com is a good example of a case where it can make fine sense to use an empty custom element that doesn't need to wrap already-functional/meaningful HTML. Those cases tend to be the exception in my experience/preference though!

In order to move beyond our industry's recurring dependence on libraries built for yesterday's browsers, we need more standards-based alternatives to the many visually-compelling resources like reactbits.dev. The influence these resources have on decison-making design engineers right now is massive.

I bought this this morning and I’m over half way through it. Probably the best $25 I’ve spent in years. I use web components for my blog posts and have known for a while that there are big gaps in my knowledge, and this has filled a whole bunch of them.
