Convert HMTL Maps to GeoJSON/JSON data

Question

I have an HTML file here, but I don't know how to extract the coordinate data into a GeoJSON or shapefile. Is there a quick way to get it? Link : https://codeshare.io/DZEwnO

function myMap() {
   ...
   };
   var features = [ 
               {
            position: new google.maps.LatLng(-6.970243, 110.423680),
            type: 'keluar',
            shelter: 'Kantor Pos Besar',
            status: 'KOTA',
            tipe: 'PERMANEN',
            arah: 'Tawang - Bawen',

         },
               {
            position: new google.maps.LatLng(-6.972159, 110.421801),
            type: 'keluar',
            shelter: 'Bata Pemuda',
            status: 'KOTA',
            tipe: 'Permanen',
            arah: 'Tawang - Bawen',
            image: 'https://gis.perhubungan.jatengprov.go.id/assets/upload/shelter/thumbs/H_Bata_Pemuda.png'
         },
               {
            position: new google.maps.LatLng(-6.975905, 110.418125),
            type: 'keluar',
            shelter: 'BCA Pemuda',
            status: 'KOTA',
            tipe: 'Permanen',

You can simply iterate over features, create GeoJSON object and then download stringified GeoJSON.

Code could look something like this:

var geojson =  {
  "type": "FeatureCollection",
  "features": []
}

features.forEach(function(feature) {
  var geoJsonFeature = {
    "type": "Feature",
    "properties": {
      "type": feature.type,
      "shelter": feature.shelter,
      "status": feature.status,
      "tipe": feature.tipe,
      "arah": feature.arah,
      "image": feature.image
    },
    "geometry": {
      "type": "Point",
      "coordinates": [feature.position.lng(), feature.position.lat()]
    }
  }
  geojson.features.push(geoJsonFeature);
});
var data = new Blob([JSON.stringify(geojson)], {type: 'text/xml'});
var fileName = 'data.geojson';
if (navigator.appVersion.toString().indexOf('.NET') > 0)
   window.navigator.msSaveBlob(data, fileName);
else {
  var url = window.URL.createObjectURL(data);
  var downloadLinkElement = document.createElement('a');
  downloadLinkElement.href = url; 
  downloadLinkElement.download = fileName; 
  downloadLinkElement.click();
}
