Sweet Alert 2括号错误和phpstorm分析

Question

我尝试使用SweetAlert2，但我认为有一些错误，因为PhpStorm IDE说。

此代码与Git Lib完全相同。

＆＃13;

＆＃13;

swal({
    title: 'Giriş Başarılı',
    text: 'İki aşamalı doğrulama aktif size bir doğrulama kodu gönderiyoruz.',
    timer: 3000,
    onOpen: () => {
    swal.showLoading()
}
}).then((result) => { if (result.dismiss === 'timer') { window.location.href = 'dogrulama-kodu'; }
})

＆＃13;

<script src="https://unpkg.com/sweetalert2@7.1.3/dist/sweetalert2.all.js"></script>

＆＃13;

＆＃13;
