Svelte

Compile-time optimized framework with no runtime overhead and small bundles

Website Docs GitHub

Created by Rich Harris, Svelte shifts work from the browser to the build step, compiling components into highly efficient imperative code. This approach eliminates the need for a virtual DOM and results in smaller bundle sizes and faster runtime performance.
