SolidJS
FreeReactive JavaScript library for building user interfaces.
What does this tool do?
SolidJS is a reactive JavaScript library for building user interfaces, designed to provide high-performance rendering with a unique approach to reactivity. Unlike traditional frameworks that use virtual DOM, Solid employs fine-grained reactivity, which means components render only once and individual reactive primitives update precisely when their dependencies change. This approach allows for extremely efficient rendering and minimal unnecessary updates, resulting in superior performance and smaller bundle sizes.
