How to use the can-connect/helpers/.forEach function in can-connect

var update = function(changes){

		helpers.forEach.call(changes, function(change){
			if(change.type === "add") {
				// Create the `todoItem` and insert it in the right spot
				var li = todoItem(todos[change.name]).hide();
				if(element.children().length) {
					element.children().eq(change.name-1).after( li );
				} else {
					element.append(li);
				}
				li.fadeIn();
			}
			else if(change.type === "delete") {
				// Find the `todoItem` to remove.
				// Trigger an event so it can tear itself down.
				// Animate and remove the `todoItem` element.
				var li = element.children().eq( change.name );
				li.triggerHandler("remove");

* });

 * var todoConnection = connect(["data-url","fall-through-cache"],{
 *   url: "/services/todos",
 *   cacheConnection: cacheConnection
 * });
