import { BrowserRouter } from "react-router-dom";
ReactDOM.createRoot(document.getElementById('root')!).render(
  <BrowserRouter>
    <App />
   </BrowserRouter>,
)

 <div>
    <Routes>
    <Route path="/" element= {<StartPage/>} />
    <Route path="/main" element={<MainPage />} />
    </Routes>
 </div>
