  render() {
    return (
      <div>
        {this.state.counter}
      </div>
    );
  }
}

export class StatefulCounter extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      counter: 0,
    };
  }

  render() {
    return (
      <div>
        {this.state.counter}
      </div>
    );
  }
}
StatefulCounter.displayName = 'StatefulCounter';

SFC Example

In

  return (
    <div>
