About Preact

Preact is a lightweight JavaScript UI library with a React-compatible component model and virtual DOM architecture. It supports hooks, context, routing integrations, and compatibility layers for many React ecosystem tools. Preact is commonly used in performance-sensitive web applications, embedded widgets, progressive web apps, and projects that want React-style development with smaller bundles.
