Preact

Preact is a lightweight JavaScript library for building user interfaces, similar to React. It allows developers to create interactive web applications by designing components—small, reusable pieces of code that manage specific parts of a webpage. Preact's small size makes websites faster to load and more efficient, especially on devices with limited resources. Despite its compactness, it offers many of the features React developers rely on, making it a popular choice for creating high-performance, dynamic websites without extra overhead.
