### Examples

### setVisitorPrimaryLocale
```javascript
import { locales } from '@wix/multilingual';

async function setVisitorPrimaryLocale(localeId) {
  const response = await locales.setVisitorPrimaryLocale(localeId);
};
```

### setVisitorPrimaryLocale (with elevated permissions)
```javascript
import { locales } from '@wix/multilingual';

### setVisitorPrimaryLocale (self-hosted)
Self-hosted SDK calls require you to [create a client](https://dev.wix.com/docs/sdk/articles/work-with-the-sdk/about-the-wix-client.md).

```javascript
import { createClient } from '@wix/sdk';
import { locales } from '@wix/multilingual';
// Import the auth strategy for the relevant access type
// Import the relevant host module if needed

const myWixClient = createClient ({
  modules: { locales },
  // Include the auth strategy and host as relevant
});


async function setVisitorPrimaryLocale(localeId) {
  const response = await myWixClient.locales.setVisitorPrimaryLocale(localeId);
};
```
