I’m surprised no-one answered with this code:

for(var child=elt.firstChild;
    child;
    child=child.nextSibling){
  do_thing(child);
}

Or, if you only want children which are elements, this code:

for(var child=elt.firstElementChild;
    child;
    child=child.nextElementSibling){
  do_thing(child);
}
