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 business = [
     "business1",
     "business2",
     "business3",
     "business4",
     "business5"
 ]


class Hello extends React.Component {
  render() {
    return (
      <div>
       {
        business.map((data,index) => {
            return index===3 ? <div>New Section</div><div>{data}</div>:<div>{data}</div>
        })
       }
      </div>
    )
  }
}

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