NumberFormat Not working

[shubhamkes]

import IntlP from 'react-native-intl';

export async function NumberFormatter() {
    const result = await (new IntlP.NumberFormat('en-US')).format(123456);
    alert(result);
}

Seems there is some issue with library or dont know what, but alert is never executed.

"react": "^16.0.0-beta.5" "react-native": "^0.49.5" "react-native-intl": "^1.0.0"

Do I need to link this library? Please help
