Advice:

If you don't like to manage your translation files manually or are simply looking for a better management solution, take a look at i18next-locize-backend. The i18next backend plugin for 🌐 Locize ☁️ — built by the same team behind react-i18next, with CDN delivery, AI translation, and no redeploys for copy changes.

What will my code look like?

Before: Your react code would have looked something like:

...
<div>Just simple content</div>
<div>
  Hello <strong title="this is your name">{name}</strong>, you have {count} unread message(s). <Link to="/msgs">Go to messages</Link>.
</div>
...

After: With the trans component just change it to:

...
<div>{t('simpleContent')}</div>
<Trans i18nKey="userMessagesUnread" count={count}>
  Hello <strong title={t('nameTitle')}>{{name}}</strong>, you have {{count}} unread message. <Link to="/msgs">Go to messages</Link>.
</Trans>
...

Why i18next?

Simplicity: no need to change your webpack configuration or add additional babel transpilers, just use create-react-app and go.
Production ready we know there are more needs for production than just doing i18n on the clientside, so we offer wider support on serverside too (nodejs, php, ruby, .net, ...). Learn once - translate everywhere.
Beyond i18n comes with Locize bridging the gap between development and translations - covering the whole translation process. Now with a Free plan for your side projects!
