What problem it solves

Building interactive user interfaces can involve coordinating views with application state and organizing interface logic into reusable units. React addresses this with a declarative, component-based approach that supports web, server, and mobile applications.

Key features

• Declarative user interfaces — Describe views for each application state and let React update the appropriate components when data changes.

  Source: README

• Component-based composition — Create encapsulated components that manage their own state and compose them into complex interfaces.

  Source: README

• Flexible platform support — Develop features without assuming a particular technology stack, with support for server rendering and mobile applications.

  Source: README

• Gradual adoption — Adopt as much or as little of the library as a project needs, from a quick introduction to integration with an existing project.

  Source: README

• Readable markup with JSX — Use an HTML-like syntax for interface markup that can make code more readable, while keeping JSX optional.

Quick start

Copied verbatim from the project's README.

import { createRoot } from 'react-dom/client';

function HelloMessage({ name }) {
  return <div>Hello {name}</div>;
}

const root = createRoot(document.getElementById('container'));
root.render(<HelloMessage name="Taylor" />);

Who it may suit

Inference: This may suit JavaScript developers who want a declarative, component-based way to build interactive web interfaces, as well as teams adding shared UI to server-rendered or mobile applications.

Topics to discuss

• Which patterns have worked well for organizing state across encapsulated components?

• How can teams adopt React gradually in an existing JavaScript application?

• What examples would help developers understand server rendering and React Native integration?
