Preact

Preact is a JavaScript library that offers a fast, lightweight alternative to React, boasting the same modern API but with a significantly smaller footprint. At just 3kB, it ensures that your application code, not the framework, constitutes the bulk of your project's size. This translates to less JavaScript for users to download, parse, and execute, leading to faster load times.

Key advantages include:

• High Performance: It's one of the fastest Virtual DOM libraries available, utilizing a simple and predictable diff implementation and automatic update batching.
• Ecosystem Compatibility: Seamlessly integrate and use thousands of components from the extensive React ecosystem by adding a simple alias to your bundler.
• Direct DOM Interaction: Provides a thin Virtual DOM abstraction, using stable platform features and real event handlers, which allows it to work well with other libraries.
• Portability: Its small size makes it perfect for embedding into widgets or parts of an existing application without complex integration.
