How does the react i18next library help manage translations in a React app?

react i18next lets you organize translated text into separate files for each language, and provides a useTranslation hook that gives your components a simple function to look up the correct translated text based on the currently selected language, including support for things like pluralization and inserting dynamic values.

import { useTranslation } from 'react-i18next';

function Greeting({ name }) {
  const { t } = useTranslation();
  return <p>{t('greeting', { name })}</p>;
}

// translation file: { "greeting": "Hello, {{name}}" }
