  }
}

export default MyComponent;

import React from 'react';

const MyComponent: React.FC = () => {

      <div>Hello</div>
      <div>World</div>
    </>
  );
};

export default MyComponent;

import React from 'react';

class MyComponent extends React.Component {
  render() {
    return [
      <div key="1">Hello</div>,
      <div key="2">World</div>

  }
}

export default MyComponent;
