React Hooks

React updates and renders only the components affected by state changes, making UIs predictable and easier to debug, as emphasized in the README's description of declarative views.

Encapsulated components with self-managed state enable building complex UIs from reusable parts, keeping logic in JavaScript and state out of the DOM, per the component-based philosophy.

React can be added incrementally to existing projects without a full rewrite, supporting use from small widgets to full applications, as highlighted in the installation section.

With React Native for mobile and server-side rendering via Node, React allows code reuse across web and native platforms, aligning with the 'Learn Once, Write Anywhere' approach.
