Hi, I've been searching but couldn't find any similar question. The server I'm using is running, but it's not working as expected from the tutorial I'm following.

I'm using the latest versions of vs code, xampp, composer, Laravel, nodejs and npm, so here's the code:

import {createBrowserRouter} from "react-router-dom";

//指定路由
const router = createBrowserRouter(routes: [])
export default router;

The colon before routes (routes:) has an underline in red and displays "expected ','". I'm following this video https://youtu.be/qJq9ZMB2Was, at about 23:02.

Thank you very much for your help, I am still learning and am a beginner in this field.

should not be underlined in red.
