Detects what the language of the current user is.

• Retrieve the current language by looking in several places of the navigator object.

const detectLanguage = () => {
  if (navigator.languages && navigator.languages.length) {
      return navigator.languages[0];
    } else {
      return navigator.userLanguage || navigator.language || navigator.browserLanguage || 'en-US';
    }
};

detectLanguage(); // "nl-NL"
