Regex format?

[mushroomgenie]

Is there any particular format in which we must write the regex expression? Because whenever I put bodyRegex, I get an empty array as response.

Hi i done some research and found out javaScript has Regular Expressions Which are basically if this Regex format is not working for you.
I have made a custom fucntion use Regular Expressions
I needed Regex to get sms which contains city , area and description change according to your needs

`const LocalSms = () => {
const [SmsCount, setSmsCount] = useState();
const [SmsBody, setSmsBody] = useState([]);

const [sms, setSms] = useState([]);
const [loading, setLoading] = useState(true);

useEffect(() => {
const fetch = async () => {
await requestSmsPermission();
read();
};
fetch();
}, []);

useFocusEffect(
React.useCallback(() => {
const fetch = async () => {
await requestSmsPermission();
read();
};
fetch();
return () => fetch();
}, [read]),
);

async function requestSmsPermission() {
try {
const granted = await PermissionsAndroid.request(
PermissionsAndroid.PERMISSIONS.READ_SMS,
{
title: 'SMS Permission',
message:
'This app needs access to your SMS messages to function properly.',
buttonNegative: 'Cancel',
buttonPositive: 'OK',
},
);
if (granted === PermissionsAndroid.RESULTS.GRANTED) {
console.log('SMS permission granted');
} else {
console.log('SMS permission denied');
}
} catch (err) {
console.warn(err);
}
}

const filter = {
box: 'inbox',
maxCount: 10,
};

const read = () => {
console.log('reading for read()');
SmsAndroid.list(
JSON.stringify(filter),
fail => console.log('Failed with error:', fail),
(count, smsList) => {
const parsedData = JSON.parse(smsList);
console.log('parsedData', parsedData);
validate(parsedData);
setSmsCount(count);
setLoading(false);
},
);
};

function validate(body) {
const regex = new RegExp('(city)|(area)|(description)');
const tempSms = [];
body.forEach(bodyData => {
if (regex.test(bodyData.body)) {
console.log('bodyData.body=', bodyData.body);
tempSms.push(bodyData.body);
}
setSmsBody(tempSms);
});
}

return (

{!loading ? (
<FlatList
showsVerticalScrollIndicator
style={styles.list}
data={SmsBody}
renderItem={({item, index}) => {
return (

{item}

);
}}
/>
) : (

<ActivityIndicator size={200} color={'#116A7B'} />
Fetching Sms

)}

);
};`
