react-table
🤖 Headless UI for building powerful tables & datagrids for TS/JS - React-Table, Vue-Table, Solid-Table, Svelte-Table
https://github.com/TanStack/table/pull/5943
IMHO, trying to teach people this level of idiosyncrasy is a bit silly, and regardless of benefit, seems unlikely to work long term.
I also agree the community is frustrating to deal with. I reported what is a blazingly clear bug (once you know it exists):
Svelte5 ships two incompatible Snippet types because of the use of unique symbols for SnippetReturn. Different unique symbols are never compatible in TS.
So these two SnippetReturn types (which are then used in the Snippet type in each file):
rg -ai ".*SnippetReturn.*unique symbol" -
NativeScript

NativeScript is a good example of a runtime built specifically for cross-platform native mobile application development built using JavaScript.

Project mention: Mitosis - Using Astro.js as the dev server to preview the component with hot-reload | dev.to | 2024-08-31Turns out there are quite a few of gotchas and open issues in using Mitosis (when this tutorial is written). Sometimes the generated code works perfectly in React and Vue but not Svelte. Sometimes the others. It would be great if

We do have pseudo-browsers written in pure js that you can theoretically use:
https://github.com/jsdom/jsdom
https://github.com/capricorn86/happy-dom
but they're about as reliable as you can expect: it's difficult to keep up the pace with the big three (or two) on standards compliance, and they usually don't even try.
So the only reliable solution is a headless Chromium, Firefox, and/or WebKit-based noname browser like the sibling says.
