In addition to each, is it possible to somehow calculate the number of li for each ul in this example?

Answer 1

Can. But no cycle.

var elements = document.getElementByTagName('ul');
for(var counter = 0; counter < elements.length; counter++){
  elments[counter].inLength = elements[counter].getElementsByTagName('li').length;
}
