How can I get my device language ?

[tranvanquang]

I want to get my device language. I try using import { getLanguages } from 'react-native-i18n';

getLanguages().then(languages => { console.log(languages); });

I receive a log: "languages: en-US,vi-US,en,vi-VN" I understand how to detect language from this log? Can I help me? Thank i so much
