Zoom changed event for nokia Here maps

I'm confused on how to handle zoom events with Nokia Here maps. Usually for example 

map.addEventListener('dragend', function(){....})

why cant the same signature work for something like 

map.addEventListener('zoomend', function(){....})

I know there is a event called mapviewchangeend but how will I use that to know if it was a zoom change rather a drag

Thanks!

The supported map events are documented here , i think simplest way to achieve your requirement would be to check the map zoom level in the mapviewchangeend listener. 

var oldZoom=map.getZoom();
map.addEventListener('mapviewchangeend', function(){
     var newZoom=map.getZoom();
     if(newZoom > oldZoom){
      // zoomed in
     }else{
      // zoomed out
     }
     oldZoom=newZoom;
})
