/*
|
||||
To Do (ho ho ho)
|
||||
spec is at: https://github.com/tastejs/todomvc/blob/master/app-spec.md
|
||||
|
||||
- file layout?
|
||||
- README
|
||||
- pattern the HTML more explicitly on the given template, keep changes to a minimum
|
||||
- code style https://github.com/tastejs/todomvc/blob/master/contributing.md#code-style
|
||||
|
||||
- no todos: make sure #main and #footer are hidden
|
||||
- mark all as complete/incomplete; make sure it is only ever checked when all the todos are checked
|
||||
- count of active todos; pluralize correctly; format correctly
|
||||
- hide "clear completed" button when no completed todos exist
|
||||
- persist to localStorage; use correct keys and name.
|
||||
|
||||
- routing: spec requires that filtering be done "on a model level";
|
||||
we, by using "hidden" class, are kind of partly doing it on a view
|
||||
level. We could either continue to do this, or switch to a proper
|
||||
model level approach, but then we'd lose stability of ordering!
