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>
<div id="container2">
    <!-- This element's contents will be replaced with your component. -->
</div>

Babel + JSX

class Hello extends React.Component {
  render() {
  	console.log(this.props.name)
    return <div>{this.props.name}</div>;
  }
}

ReactDOM.render(
  <Hello name="&lt;p&gt;How are you?&lt;/p&gt;" />,
  document.getElementById('container')
);


class HelloOther extends React.Component {
  render() {
  	const name = "&lt;p&gt;How are you?&lt;/p&gt;" 
    return <Hello name={name} />;
  }
}

ReactDOM.render(
  <HelloOther />,
  document.getElementById('container2')
);
