    }
}

    }
}

// Example usage:

    } catch (error) {
        console.error("Error:", error.message);
    }
}

// Example usage:
states();
```

```javascript
const {getCities} = require("state_city_pincode");

// Use the pincodeLookup function to retrieve pincodes
function cities(state) {
    try {
        console.log(getCities(state))
    } catch (error) {
        console.error("Error:", error.message);
    }
