I went with Svelte when I built out the website for my canvas library a few years back[1]. It's proved to be easy to maintain the site, and I particularly like that it supported my vanilla JS library (which I use on the site's landing page) with minimal fuss.
At some point I want to update the site to use Sveltekit, which I'd been experimenting with in personal projects. But then the team announced Svelte 5 and these things called "runes" and ... I don't know. Having just passed my 60th birthday I'm getting to a stage in my life when keeping up with all the New Shiny makes me wonder if it's worth the effort, or if I should be doing more interesting stuff like creating new content for the site instead.
