Как улучшить Route, react?

export getRoutes = permissions => routes.filer(route => route.permission ? permissions.includes(permission) : true);

export default function SwitchWithRoutes({ routes, checkHasAccess }) {
  return (
    <Switch>
      {routes.map((route, i) => {
       
         if(checkHasAccess(route.permissions) {
           return (
             <Route
               key={i}
               exact={route.path === '/'}
               path={route.path}
               component={route.component}
             />);
          }
          return null;
      })}
    </Switch>
  );
}

const mapStateToProps = state => ({
  checkHasAccess: checkHasAccessSelector(state),
});

export default connect(mapStateToProps)(SwitchWithRoutes);

const routes = [
   ...
  {
    path: '*',
    component: MyNotFoundСomponent,
  }
];
