status === PermissionAndroid.RESULTS.GRANTED would be checking text against an object.

[maniac-tech]

          from what I have seen, status in this case would return 

{
  "android.permission.RECEIVE_SMS": "granted",
  "android.permission.READ_SMS": "denied"
}

so status === PermissionAndroid.RESULTS.GRANTED would be checking text against an object.

this can be rewritten as:

const status = await PermissionsAndroid.requestMultiple([
  PermissionsAndroid.PERMISSIONS.RECEIVE_SMS,
  PermissionsAndroid.PERMISSIONS.READ_SMS,
]);

const granted = PermissionsAndroid.RESULTS.GRANTED;
const denied = PermissionsAndroid.RESULTS.DENIED;
const neverAskAgain = PermissionsAndroid.RESULTS.NEVER_ASK_AGAIN;

if (status[PermissionsAndroid.PERMISSIONS.RECEIVE_SMS] === granted &&
    status[PermissionsAndroid.PERMISSIONS.READ_SMS] === granted) {
  return true;
}

if ([status[PermissionsAndroid.PERMISSIONS.RECEIVE_SMS], status[PermissionsAndroid.PERMISSIONS.READ_SMS]].includes(denied)) {
  console.log("Read/Receive SMS permission denied by user.", status);
} else if ([status[PermissionsAndroid.PERMISSIONS.RECEIVE_SMS], status[PermissionsAndroid.PERMISSIONS.READ_SMS]].includes(neverAskAgain)) {
  console.log("Read/Receive SMS permission revoked by user.", status);
}
