Leveraging Google Geocode data beyond the scope of Vue.js functionality

Currently, I am immersing myself in learning Vue.js and exploring the world of Google Maps and geocoding. My current challenge revolves around translating a location into latitude/longitude results. While my code successfully fetches the desired data from Google, I'm facing an issue with accessing variables outside of the if statement. This has left me feeling a bit puzzled and seeking assistance to further enhance my understanding.

        var geocoder = new window.google.maps.Geocoder();
                var address = "Dublin";
               geocoder.geocode( { 'address': address}, function(results, status) {
                if (status == window.google.maps.GeocoderStatus.OK) {
                  var latitude = results[0].geometry.location.lat();
                  var longitude = results[0].geometry.location.lng();
                  console.log(latitude) // Correct data is returned
                  console.log(longitude) // Correct data is returned
                  this.me = longitude
                          } 
                  }); 
                console.log(this.me) // Does not return anything!!
 console.log(longitude) // Does not return anything!!

Your inquiry primarily deals with the use of this. Utilizing an arrow function instead of a regular function can help in correctly referencing 'this'.

var geocoder = new window.google.maps.Geocoder();
                var address = "Dublin";
               geocoder.geocode( { 'address': address}, (results, status) => {
                if (status == window.google.maps.GeocoderStatus.OK) {
                  var latitude = results[0].geometry.location.lat();
                  var longitude = results[0].geometry.location.lng();
                  console.log(latitude) //returns correct data
                  console.log(longitude) //returns correct data
                  this.me = longitude
                          } 
                  }); 
                console.log(this.me) //returns nothing!!
                 console.log(longitude) //returns nothing!!

I have not executed the code myself, but based on the snippet provided, it should function as intended.
