reactjsHow do I use the ReactJS documentation to get started with ReactJS development?


ReactJS documentation is a great resource to get started with ReactJS development. To get started, you need to include the React library in your HTML page. You can use a CDN or download it from the React website.

<script src="https://unpkg.com/react@16/umd/react.development.js" crossorigin></script>
<script src="https://unpkg.com/react-dom@16/umd/react-dom.development.js" crossorigin></script>

Once you have included the React library, you can start creating React components. A React component is a JavaScript class or function that optionally accepts inputs called props and returns a React element that describes how a section of the UI (User Interface) should appear.

class Hello extends React.Component {
  render() {
    return <h1>Hello, {this.props.name}</h1>;
  }
}

ReactDOM.render(
  <Hello name="World" />,
  document.getElementById('root')
);

Output example

<h1>Hello, World</h1>

To learn more about React components, refer to the React Components documentation. The React documentation also contains information about state and lifecycle, hooks, events, and much more.
