Web Components are a great way to implement things that the browser should have already implemented, like accordions, combo boxes, and date pickers that don’t suck. It’s been a pleasure to use them in a mostly static, content-heavy Astro site.

But beyond that, they’re not really usable without a framework that can deal with state and reactivity across a whole application. And that’s fine! They fill a good niche. But just because the browser provides an API doesn’t mean it should be used whenever possible.
