Overview

What is Solid.js?

Solid.js is a declarative, performant JavaScript UI library. Unlike React, it compiles to efficient DOM operations without a virtual DOM, achieving near-vanilla-JS performance. It shares React's composition model and JSX syntax but with fine-grained reactivity baked in.
