How to access current locale in React app using react-intl? 

To access the current locale in a React app using react-intl, you can look for it at the top of the component tree where the IntlProvider component is configured. This component requires both the locale and messages props to be set up properly.

If you need access to the current locale in other parts of your app, you can pass the locale down the component tree from where the IntlProvider is configured. This makes it possible to use the current locale for other purposes throughout your application.

<IntlProvider locale={locale} messages={messages}>
  <App />
</IntlProvider>

It's important to note that in some React applications, the currently selected locale information may be saved on the server. This means that the fetched user data from the server might include such information.
