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

const rolesMap = {
 a: <div>Component A</div>,
 b: <div>Component B</div>,
 c: <div>Component C</div>,
}

class Hello extends React.Component {
  render() {
		const roles = ['a', 'b'];

		return roles.map(role => rolesMap[role])
  }
}

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