ReactJS: A JavaScript Library

A JavaScript library for building user interfaces.

Design simple views for each state in your application, and React will efficiently update and render just the right components when your data changes.

Declarative views make your code more predictable and easier to debug.

This is an example of ReactJS code:

class HelloMessage extends React.Component {
  render() {
Hello {this.props.name}
; } } root.render();
