React

React is the standard library for building user interfaces. React 19 (2025) introduces a new era with the React Compiler, Server Components, and Actions.

When to Use

• Single Page Apps (SPA): Rich, interactive dashboards.
• Complex UI: Applications with many moving parts and state.
• Ecosystem: When you need the largest library of 3rd party components.

Quick Start (React 19)

import { use, Suspense } from "react";
