How can I determine the direction of a jQuery scroll event?

Question

I\'m looking for something to this effect:

$(window).scroll(function(event){
   if (/* magic code*/ ){
       // upscroll code
   } else {
      // downscrol

Since bind has been deprecated on v3 ("superseded by on") and wheel is now supported, forget wheelDelta:

$(window).on('wheel', function(e) {
  if (e.originalEvent.deltaY > 0) {
    console.log('down');
  } else {
    console.log('up');
  }
  if (e.originalEvent.deltaX > 0) {
    console.log('right');
  } else {
    console.log('left');
  }
});
