What is it all about?
Svelte is a radical new approach to building user interfaces. Whereas traditional frameworks like React and Vue do the bulk of their work in the browser, Svelte shifts that work into a compile step that happens when you build your app.
Instead of using techniques like virtual DOM diffing, Svelte writes code that surgically updates the DOM when the state of your app changes.

— Svelte components are built on top of HTML. Just add data. — CSS is component-scoped by default — no more style collisions or specificity wars. — Trigger efficient, granular updates by assigning to local variables. The compiler does the rest — Build beautiful UIs with a powerful, performant transition engine built right into the framework.
