Passing JS getCurrentPosition to global variable

Question

I am building an app that requires user location, to achieve this i am using:

var options = {
    enableHighAccuracy: true,
    timeout: 5000,
    maximumAge: 0
};

function success(pos) {
    var crd = pos.coords;
    console.log('Your current position is:');
    console.log(`Latitude : ${crd.latitude}`);
    console.log(`Longitude: ${crd.longitude}`);
    console.log(`More or less ${crd.accuracy} meters.`);
    console.log(` ${crd.longitude}`);
 }

function error(err) {
    console.warn(`ERROR(${err.code}): ${err.message}`);
    console.log(`Latitude : 9`);
}

navigator.geolocation.getCurrentPosition(success, error, options);

How can i pass the user lattitude and longitude to a global variable?

You can use local storage for an optimize solution.

var options = {
    enableHighAccuracy: true,
    timeout: 5000,
    maximumAge: 0
};

function success(pos) {
    var crd = pos.coords;
    console.log('Your current position is:');
    console.log(`Latitude : ${crd.latitude}`);
    console.log(`Longitude: ${crd.longitude}`);
    console.log(`More or less ${crd.accuracy} meters.`);
    let userLatitude = crd.latitude;
    let userLongitude = crd.longitude;
    localStorage.setItem("USER_LATITUDE", userLatitude);
    localStorage.setItem("USER_LONGITUDE", userLongitude);
    console.log(` ${crd.longitude}`);
 }

function error(err) {
    console.warn(`ERROR(${err.code}): ${err.message}`);
    console.log(`Latitude : 9`);
}

navigator.geolocation.getCurrentPosition(success, error, options);

If you want to use this location data;

var latitude = localStorage.getItem('USER_LATITUDE');
var longitude = localStorage.getItem('USER_LONGITUDE');
