How can i keep state in a React component using ES6

Question

I\'m trying to use a stateful React component with ES6 but when I define a constructor the constructor will only be called once while the component is rendered multiple time

You SubComponent should be:

 class SubComponent extends React.Component {
      constructor(props) {
        super(props);
        console.log("Creating sub component");
      }

      render() {
        return (
count: {this.props.count}
);
      }
    }
