React

Specifically interested in Component <Props>How is understood <Props>?

};

export default class Root extends Component<Props> {
  render() {
    return (
      <Provider store={this.props.store}>
        <ConnectedRouter history={this.props.history}>
          <Routes />
        </ConnectedRouter>
