Data-driven DOM manipulation: select elements and join them to data.

import pointer from "./pointer.js";
import sourceEvent from "./sourceEvent.js";

export default function(events, node) {
  if (events.target) { // i.e., instanceof Event, not TouchList or iterable
    events = sourceEvent(events);
    if (node === undefined) node = events.currentTarget;
    events = events.touches || [events];
  }
  return Array.from(events, event => pointer(event, node));
