There's a better explanation of the differences here: https://svelte.dev/blog/svelte-3-rethinking-reactivity Svelte is a component framework — like React or Vue — but with an important difference. Traditional frameworks allow you to write declarative state-driven code, but there's a penalty: the browser must do extra work to convert those declarative structures into DOM operations, using techniques like that eat into your frame budget and tax the garbage collector.
Instead, Svelte runs at build time, converting your components into highly efficient imperative code that surgically updates the DOM. As a result, you're able to write ambitious applications with excellent performance characteristics.
