I've been doing React for about 10 years. Just started playing with Svelte 5 a few days ago.
It's so simple to work with. Built a simple stock allocation app and what surprised me most was the bundle size... 9kb (gzip). That's better than any other framework I am aware of. That's even smaller than htmx which is somewhat "anti-js"
I think svelte 5 is an actual innovation, it does not behave or feel like a “framework” to me. It feels like a natural extension of building an front end with raw html, css, js, solving the headaches you eventually hit when you do so.
