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 FirstImage = () => <div><img 
src="https://www.import.io/wp-content/uploads/2017/10/React-logo-1.png" crossOrigin="anonymous"/></div>

const SecondImage = () => <div><img 
src="https://www.import.io/wp-content/uploads/2017/10/React-logo-1.png" crossOrigin="anonymous"/></div>

class Hello extends React.Component {
	state={secondImage: false}
 
  changeImage = () => {
    this.setState({secondImage: !this.state.secondImage})
  }
 
  render() {
    return <div><button onClick={this.changeImage}>Reload</button>        {!this.state.secondImage ? <FirstImage/> : <SecondImage></SecondImage>}</div>;
  }
}

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