Detects what the language of the current user is. Detects the preferred language of the current user.
- Retrieve the current language by looking in several places of the navigator object. - Use `NavigationLanguage.language` or the first `NavigationLanguage.languages` if available, otherwise return `defaultLang`.
- Omit the second argument, `defaultLang`, to use `'en-US'` as the default language code.
```js ```js
const detectLanguage = () => { const detectLanguage = (defaultLang = 'en-US') =>
if (navigator.languages && navigator.languages.length) { navigator.language ||
return navigator.languages[0]; (Array.isArray(navigator.languages) && navigator.languages[0] ) ||
} else { defaultLang;
return navigator.userLanguage || navigator.language || navigator.browserLanguage || 'en-US';
}
};
``` ```
```js ```js
detectLanguage(); // "nl-NL" detectLanguage(); // 'nl-NL'
``` ```
