What is SvelteKit?

Editorial review
Svelte is a modern UI framework that distinguishes itself by compiling your code into small, vanilla JavaScript bundles at build time, rather than relying on a runtime framework in the browser. This approach results in exceptionally fast and lightweight web applications with minimal overhead, making it attractive for developers seeking high performance and a smooth user experience. It allows developers to write components using standard HTML, CSS, and JavaScript, offering a familiar and intuitive development experience. Svelte is praised for its conciseness and efficiency, consistently ranking high among developers for its innovative compiler-based architecture. It's suitable for building a wide range of web applications, from simple UIs to complex interactive experiences, and is backed by a strong community and organizations like Vercel.
