IMHO you're on HN and reading this, and know about React or Vue, then give Svelte 5 a look. It's easy to pick up because Svelte uses all the HTML, CSS, and JS/TS that you already know. And Svelte 5 works with SvelteKit, which is a great framework for apps, including routers, caches, SSR, etc.
Vue was the same, vue 1 was simple and you could get going within minutes, svelte had the same feeling first time I used it, but now looking at version 5, it still looks simple, but seems to start leaning towards the same route vue took..
Personally, I like to stay as close to web standards as possible, instead of tying myself to specific implementations of specific addons for specific frameworks.
React is the closest to standard JS in my experience.
Svelte is built to not require this abstraction (VDOM), which increases the likelihood that it will work with other JS libraries out of the box.
I don't think this is what happened with Svelte though. I never used v1 but v5 simplified and distilled a lot of things vs v3 (and v4 which was almost identical).
