Why is the value not written to the variable?

Question

JavaScript

Good afternoon everyone. Why can't I write the coordinate value to the position variable declared at the very beginning of the geocode function??

var position,
    geocoder = new google.maps.Geocoder();

  geocoder.geocode({
    'address': address
  }, function(results, status) {
    if (status === google.maps.GeocoderStatus.OK) {
      position = results[0].geometry.location;
console.log(position);// Все ок, координаты записаны, карта показалась!
      map.panTo(position);
    } else {
      alert('Адрес указан не верно: ' + status);
    }
  });
console.log(position); // А тут они undefined, разве я не записал значение в переменную?

Why is that?

Because geocoder.geocode is an asynchronous function, and when you output position at the end, the value isn't there yet. Go read about the basics of JS, otherwise you will ask such questions every day.
