Lightweight and intuitive javascript library

// Call an event manually on all the nodes
u.prototype.trigger = function (events) {
  var data = this.slice(arguments).slice(1);

  return this.eacharg(events, function (node, event) {
    var ev;

    // Allow the event to bubble up and to be cancelable (as default)
    var opts = { bubbles: true, cancelable: true, detail: data };

    try {
      // Accept different types of event names or an event itself
      ev = new window.CustomEvent(event, opts);
    } catch (e) {
      ev = document.createEvent('CustomEvent');
      ev.initCustomEvent(event, true, true, data);
    }

    node.dispatchEvent(ev);
  });
};
