To translate dynamic data in React, use a library like `react-i18next`. First, install it and set up your translation files. Wrap your app with the `I18nextProvider` and initialize `i18n`. Use the `useTranslation` hook in your component to easily translate text. For example: `const { t } = useTranslation(); return <p>{t('key')}</p>`. Pass the dynamic data into your translation string using interpolation, e.g., `t('greeting', { name: userName })`.
