### What will my code look like?

**Before:** Your react code would have looked something like:

```jsx
...
<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:

```jsx
...
<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](https://www.i18next.com/overview/supported-frameworks) too (nodejs, php, ruby, .net, ...). **Learn once - translate everywhere**.
- **Beyond i18n** comes with [locize](https://locize.com) bridging the gap between development and translations - covering the whole translation process.
