Insulin was invented ~100 years ago, and its patent sold for $1. “Do you know the reason why [insulin is] $1,000 with insurance?” ~Alexandria Ocasio-Cortez There is no reason for insulin to cost $21 in Canada for a 10 ml bottle, while it costs a mortgage payment in the US.

Custom element authors can attach one or more "parts" to any element inside the shadow root. Those parts can then be styled by consumers using ::part(name). Fun fact: CSS parts are a lot like classes. In fact, they both use the DOMTokenList API!

Just watched 〚...LOVE〛- all day. err day. - HIPHOP and CODE’s talk on Web Components. Saw some name drops for Cory LaViska (Shoelace) and Westbrook 😄 youtu.be/JFotV9Fb6cI

This is a very useful feature! If you are working with #webcomponents and you are focused within it, it will return the web component as the "active element". You can get the focused element within the component using "element.shadowRoot.activeElement".

me: notices the new GitHub repo UI feels *great* 👀 inspects 👀 one weird trick: #webcomponents

Could it be “yes and”? Eg… able to use the same web components in a React driven view vs having to “port”?

#lazydev I remember seeing research as to the perf differences of a single master Mutation Observer for all things vs many focused ones...anyone have a lead or did I make it up?

Westbrook Passle Independent render roots is a big advantage, actually. It just naturally leads to scoping / pruning of updates, incremental hydration, and all kinds of good things. The assumption that there needs to be central control needs to be broken across the framework world.

Lit might be a fair comparison to React, but there still shouldn't be a rivalry. You can use both and work together, and enhance each other. It'd be great if the React team shipped CE support which is already done btw. We've been waiting since React 16/17

Now shipping: <is-land> v3.0.0 Adds support for Declarative Shadow DOM, `defer-hydration` attribute, performance improvements on `<is-land>` without loading conditions. Thank you Elliott Marquez and @develwoutacause! Learn more: github.com/11ty/is-land/r…

The most important thing I learned after Uvalde is that there are over 50,000 school police officers in this country, but they haven't stopped even one school shooting. Instead they've arrested over 1 million kids, mostly students of color.

Why can't I use symbols as event names? I thought this was a thing. Is it not a thing?

Super interesting stuff already at the Modern Frontends Live! November 17-18 - London conf. Not even an hour passed before being told react is slow 😂😂

⚠️🚨⚠️ When tools intervene between you and your access to the web platform, proceed with caution. Ask not only: How well does it work? But also: How well does it fail? Not only: What features do they provide? But also: What features do they prevent? ⚠️🚨⚠️
