Improved / efficient code for multiple if - React Native - react-native

Question

I´m a technical project manager coordinating developers. My coding skills are limited and so I align with my devs on logical structure. For a mobile app (React Native to serve Android and iOS) we are currently developing user current location logic. Turned out we have specific Android and iOS settings, what may require native developmetn for location service handling.
I´m currently reviewing the following pseudocode and, besides others, concerned about the MULTIPLE IF statements and thinking if there is a more efficient way, as here we seem to jump into every IF, even when location is set already before.
I think there can be something like "until", "break" or similar .. and maybe relevant to consider the specific dev language, React Native in that case?
Any help, as pseudocode or if possible to make it specific already considering React Native, is very much appreciated.
Many thanks in advance!
Code
////Central Location Service to get current location.
var currentLocation;
var locationType
if Android {
DEFINED_ACCURACY = QUALITY_BALANCED_POWER
} else id iOS {
DEFINED_ACCURACY = kCLLocationAccuracyHundredMeters
}
DEFINED_DISTANCE = 3000
function startLocationService(){
var locationservice = LocationService()
locationservcie.accuracy = DEFINED_ACCURACY
locationservcie.distance = DEFINED_DISTANCE
locationservcie.startListnertoLocationUpdate() {
cacheData(location, currentTime);
currentLocation = location
}
}
function getLocationFromLocationService() {
if locationServcieEnabled == false
return NULL;
if locationPermissionGranted == false
return NULL;
return currentLocation;
}
function getCurrentLocation() {
var lcoation = NULL;
var accuracy = Not_defined;
lcoation = getLocationFromLocationService() //GPS, network
locationType = locationService
if lcoation == NULL {
locationdata == getLastKnownLocation()
if locationdata.Age < DEFINED_DURATION {
location = locationdata.location
locationType = locationService
}
}
if location == NULL {
location == getCachedLocationWithin24Hour()
locationType = locationService
}
if location == NULL {
location = getLocationfromTelephony()
locationType = other
}
if location == NULL {
if permissionToUseBilling == false {
askForPermissionToUseBilling()
}
location = getLocationFromBillimg()
accuracy = other
}
if location == NULL {
location = getLocationOfDEfaultCountry()
accuracy = other
}
return location, Other
}

I think you can use switches to cover different cases from javascript.
Probably your dev team knows, but did not want to bring it into pseudo code?
const location = getLocationFromLocationService() ;
switch (location) {
case 'NULL':
//DO SOMETHING WHEN NULL;
break;
case 'New York':
// DO SOMETHING WHEN New York;
// No break leads to run also into the next case
case 'Bern':
console.log('I love nice cities.');
break;
default:
console.log(`Sorry, we are out of ${location}.`);
}
Interestingly you seem to have multiple times the same if case?
Maybe you will to nest it or have to use a switch with multiple expressions.
case ("Bern" && "ANOTHERExpression to be true"):

Please don't underestimate your dev team. ;-)
