How you use decorators in React?

@setTitle('Profile')
class Profile extends React.Component {
  //....
}

/*
title is a string that will be set as a document title
WrappedComponent is what our decorator will receive when
put directly above a component class as seen in the example above
*/
const setTitle = (title) => (WrappedComponent) => {
  return class extends React.Component {
    componentDidMount() {
      document.title = title;
    }

    render() {
      return <WrappedComponent {...this.props} />;
    }
  };
};
