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

class Hello extends React.Component {
  constructor() {
    super();
    this.state = {
      data: [
        {id: 489, name: "Nickname"},
        {id: 345, name: "Email"}
      ]
    };
  }
  
  render() {
    return (
      <div>
        {
          this.state.data.map((dat, index) => {
            return (
              <div>{dat.name}</div>
            )
          })
        }
      </div>
    )
  }
}

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