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

If anyone also needs the name of the language for user selection (created from here using query selector so it's accurate):

Answer 2

This list is defined by the ISO : http://en.wikipedia.org/wiki/List_of_ISO_639-1_codes

Answer 3

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

Answer 4

Or if you need an enum of languages without locale in typescript or plaint object in javascript for copy-paste purposes

export enum ISOLanguages {
  AF = 'af',
  SQ = 'sq',
  AR = 'ar',
  EU = 'eu',
  BG = 'bg',
  BE = 'be',
  CA = 'ca',
  ZH = 'zh',
  HR = 'hr',
  CS = 'cs',
  DA = 'da',
  NL = 'nl',
  EN = 'en',
  ET = 'et',
  FO = 'fo',
  FA = 'fa',
  FI = 'fi',
  FR = 'fr',
  GD = 'gd',
  DE = 'de',
  EL = 'el',
  HE = 'he',
  HI = 'hi',
  HU = 'hu',
  IS = 'is',
  ID = 'id',
  IT = 'it',
  JA = 'ja',
  KO = 'ko',
  LV = 'lv',
  LT = 'lt',
  MK = 'mk',
  MT = 'mt',
  NO = 'no',
  PL = 'pl',
  PT = 'pt',
  RM = 'rm',
  RO = 'ro',
  RU = 'ru',
  SZ = 'sz',
  SR = 'sr',
  SK = 'sk',
  SL = 'sl',
  SB = 'sb',
  ES = 'es',
  SX = 'sx',
  SV = 'sv',
  TH = 'th',
  TS = 'ts',
  TN = 'tn',
  TR = 'tr',
  UK = 'uk',
  UR = 'ur',
  VE = 've',
  VI = 'vi',
  XH = 'xh',
  JI = 'ji',
  ZU = 'zu',
}
