function reverseGeocode(latitude, longitude) {
    let apikey = "your API key goes here";
    fetch('https://api.opencagedata.com/geocode/v1/json'
        + '?'
        + 'key=' + apikey
        + '&q=' + encodeURIComponent(latitude + ',' + longitude)
        + '&pretty=1'
        + '&no_annotations=1')
     .then((response) => response.json())
     .then((data) => alert(data.results[0].formatted));
}

function success(data) {
    let latitude = data.coords.latitude;
    let longitude = data.coords.longitude;
    reverseGeocode(latitude, longitude);
}

if (navigator.geolocation) {
    window.navigator.geolocation
        .getCurrentPosition(success, console.error);

function getReverseGeocodingData(lat, lng) {
    var latlng = new google.maps.LatLng(lat, lng);
    // This is making the Geocode request
    var geocoder = new google.maps.Geocoder();
    geocoder.geocode({ 'latLng': latlng },  (results, status) =>{
        if (status !== google.maps.GeocoderStatus.OK) {
            alert(status);
        }
        // This is checking to see if the Geoeode Status is OK before proceeding
        if (status == google.maps.GeocoderStatus.OK) {
            console.log(results);
            var address = (results[0].formatted_address);
        }
