What Is Svelte?
Svelte Compiler Framework
Svelte is a UI framework that compiles components into efficient vanilla JavaScript at build time, eliminating the need for a virtual DOM or runtime framework. The result is smaller bundles and faster performance. SvelteKit is its full-stack framework.
How Svelte Works
Svelte shifts work from runtime to compile time. Where React ships a runtime library and reconciles a virtual DOM, Svelte compiles your components into surgical DOM updates. The result: smaller bundles, faster load times, and less JavaScript for the browser to execute.
Key Concepts
- Compiler-First — Svelte compiles components at build time — no runtime library shipped to the browser
- Reactive Declarations — $: label marks reactive statements that automatically re-run when dependencies change

Frequently Asked Questions
Should I use Svelte for a new project?
Svelte is excellent for personal projects, content sites, and apps where bundle size matters. For enterprise apps or large teams, React or Vue have larger ecosystems and more available developers.
