// create(status)
let err = create(404);
err; // $ExpectType HttpError
err.name; // $ExpectType string
err.message; // $ExpectType string
err.status; // $ExpectType number
err.statusCode; // $ExpectType number
err.expose; // $ExpectType boolean
err.headers; // $ExpectType { [key: string]: string; } | undefined
// create(status, msg)
err = create(404, 'LOL');
// create(status, props)
err = create(404, {id: 1});
// create(status, props) with status prop示例2: return
