Implementing translation in React.js involves using libraries like `react-i18next`. First, install the library using `npm install react-i18next i18next`. Next, configure `i18next` with your translation files. Wrap your app with `I18nextProvider` and use the `useTranslation` hook to access translations in your components. Example: `const { t } = useTranslation();` `t('key')` will fetch the translated text. This setup allows you to maintain translations and switch languages easily.
