how to fix try catch in reactjs-CodePudding

const Login =()=> {

    const navigate = useNavigate();

    const [Data, setData] = useState({
        email:"",
        password:""
    });

    const {email,password}= Data;

    const onChangedata = (e)=> {
        
        setData({...Data,[e.target.name]:e.target.value});
    }

    const submitdata = async (e)=> {
        e.preventDefault();
       try {
  console.log(window.device.version)
} catch (e : TypeError) {
  console.log('Error')
}
    }
