How to get android system language in js?

Question

JavaScript

I made an application from the site, how to get the language of the android system using js, to change the language of the site?

Answer 1

var userLang = navigator.language || navigator.userLanguage;

Answer 2

The browser does not provide access to the system Browser has an
Accept-Language header on the back

There is an experimental api

In any case - nothing can be forced to change
You can suggest changing the language to "more suitable"
