Can onload event fire right after setting image src attribute?

Question

What console log can be after this code will be executed?

var img = new Image;
img.onload = function() { console.log('B'); };
img.src = 'image.jpg';
for (var i=0;i<100000;i++) {
  console.log('A');
}

I know, that most likely it will be A...AB . But can it be A...B...A or BA...A ? For example, if image.jpg is very small file and connection is very fast.

Answer 1

It can be any of them. You don't know how long it takes to load the image. The image could even be cached, minimizing the loading time.
