Knockout.js Gotchas

1. Knockout's observableArray dependency tracking breaks if you bind with a call to sort,reverse, etc.
1. Therefore don't do things like data-bind="foreach items.sort()", you instead bind normally with sortedItems() and then create a computed property sortedItems that sorts items. Be careful though this technique will sort items in place and not just the new computed property sortedItems.
