Jotai Has a Free API — Atomic State Management for React

What if each piece of React state was an independent atom — composable, derivable, and re-rendering only what uses it?

Jotai is an atomic state management library for React — like useState across components.

• Atomic model — each piece of state is an atom
• Minimal re-renders — only components using a specific atom re-render
• Derived atoms — computed values from other atoms
• 2 KB — incredibly lightweight

A form-heavy app had 50+ inputs re-rendering on every keystroke via Context. After Jotai atoms (one per field), input lag disappeared.
