navigator.language list of all languages

Question

Where i can see the list of languages and their codes?

I want to compare languages and auto-select required language in template.

Are they cross-browser equal?

Answer 1

In some case, navigator.language can return something like "sr-Latn-RS"

According to MDN (https://developer.mozilla.org/en-US/docs/Web/API/NavigatorLanguage/language) navigator.language can return every value valid in BCP-47: https://tools.ietf.org/html/bcp47
