Javascript translation not working

Hello i'm having issue how i can manage the translation of text inside javascript to be used by language file

HTML Code:

---

KTApp.blockPage({
                overlayColor: '#000000',
                state: 'danger',
                message: "{{ __('language.PLEASE_WAIT') }}"

It shows message {{ __('language.PLEASE_WAIT') }}

---

1) You're title is wrong... Java is not Javascript and JAvascript is not Java...
2) There should be a translation file with a PLEASE_WAIT entry in it ...
