# hasRegisteredLocale

Check whether an exact locale tag exists in the global i18n registry

## Import

```tsx
import { hasRegisteredLocale } from "@videojs/react/i18n";
```

`hasRegisteredLocale` returns whether a normalized locale tag has an explicit registry layer from [`registerI18n`](https://videojs.org/docs/framework/react/reference/api/register-i18n). It does **not** indicate whether a lazy built-in pack exists. Only registry entries count.

```ts
import { hasRegisteredLocale, registerI18n } from '@videojs/react/i18n';

hasRegisteredLocale('fr'); // false until registered
registerI18n('fr', { buttons: { play: 'Lecture' } });
hasRegisteredLocale('fr'); // true
```
