def import_locale_map
  json = JSON.parse(File.read(path_to_json))

  json["countries"].each_pair do |country_code, country_data|
    country_name = country_data["name"]
    languages = country_data["locales"]

    associate_country_with_locales(country_name, country_code, languages)
  end
end

#locale_country_codes(l) ⇒ Object

Returns an array of country codes that match the given locale code.

Note: Since in our current mapping, “en” is not assigned to any country, so “en” will not match anything while “en-us” will return “us”.
