Here is a .render() method that returns an HTML-like JSX element:

class Example extends React.Component {
  render() {
    return <h1>Hello world</h1>;
  }
}

You’ve seen render methods return <div></div>s, <p></p>s, and <h1></h1>s, just like in the above example.

Render methods can also return another kind of JSX: component instances.

class OMG extends React.Component {
  render() {
    return <h1>Whooaa!</h1>;
  }
}

class Crazy extends React.Component {
  render() {
    return <OMG />;
  }
}

In the above example, Crazy‘s render method returns an instance of the OMG component class. You could say that Crazy renders an <OMG />.
