React Base Fiddle (JSX)

Starting point for creating JSFiddles with React.

HTML

<script src="https://unpkg.com/react@16/umd/react.development.js"></script>
<script src="https://unpkg.com/react-dom@16/umd/react-dom.development.js"></script>
<div id="container">
    <!-- This element's contents will be replaced with your component. -->
</div>

Babel + JSX

function Hello() {
  	const [s, setS] = React.useState(1);
    
    console.log(React.version)
    
    const print = () => {
    	setS(s + 1);
      setTimeout(() => {
      	window.print();
      }, 600);
      window.onafterprint = () => {
      	setS(s - 1);
      }
    }
    return <div>{s}<button onClick={print}>print</button></div>;
}

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