I think i'm about a chapter behind you. I'll add devex extends to TSX/JSX itself too, the editor support and language server experience is miles ahead. Alternative formatters/linters like Deno, Biome, oxc etc. all have great support out of the box too, not so much for svelte. For when react is a bad match; I'm investigating solid instead for this reason. The svelte ecosystem is in a particularly unfortunate spot right now comprising of single/few author projects that were starting to stabilise but now have a svelte 4 -> 5 migration shaking things up.
