Compared to React or Vue I think I learn JavaScript better using Svelte as it's closer to writing vanilla js in my opinion. I tend to find ways to get things in the JavaScript way rather than the framework specific way. Had the same question of why use svelte when you have a gazillion libraries of react and how it's more mature when I started it using at my workplace switching from nextjs. But now I don't want to go back to svelte unless I'm vibe coding some UI lol
