// Some event attached to a parent element
this.parent.addEventListener('click', this.handleItemsClick.bind(this), false);


function handleItemsClick(e) {
   // e.currentTarget is the element that the event was attached to. this.parent here
   
    for (var target = e.target; target && target !== e.currentTarget; target = target = target.parentNode) {
      if (target.matches('.child-selector')) {
        // Do whatever
        break;
      }
