import axios from "axios";

const [playlist_id, setPlaylistId] = useState([]);
const [href, setHref] = useState([]);
const [playlists, setPlaylists] = useState([]);
const [isMounted, setIsMounted] = useState(false);

useEffect(() => {
    const getTracks = async (token) =>{
    const {tracks} = await axios.get("https://api.spotify.com/v1/playlists/4FteCV6SQS8yKc6pzFlZnv/tracks", {

        console.log({tracks})
