Presently, Can.Observe.List has methods to join two lists and reverse the list:
can.extend(list.prototype, {
join : [].join,
reverse: [].reverse,
}
Support for sorting is absent, but a very simple patch would enable sorting, wouldn't it?
can.extend(list.prototype, {
join : [].join,
reverse: [].reverse,
sort: [].sort,
}/Cajo.
