I don't find the way ton fix my issue. I want a specific state if the route is '/blablabla/:id'. I know how to find the simple route as '/blabla'. With a if statement is ok but i need to use switch case. Thanks for your help

 useEffect(() => {
    switch (location.pathname) {
      case '/':
        setTitle('My Board');
        break;
      case '/offers':
        setTitle('My Offer');
        break;
      case '/invoice':
        setTitle('Invoices');
        break;
      case location.pathname.match(/\d+$/): -- The route is /invoice/:id --> the id is a number 
        setTitle('Invoice Number ***');
        break;
      default:
        setTitle('My Board');
    }
  }, [location]);
