 In the case of our todo application, the view-model needs a few things: it needs to track a running list of todos and a field for adding new todos, and it needs to handle the logic of adding to the todo and the implications of this action of the UI.
 
-```javascript
-//define the view-model
-todo.vm = (function() {
-	var vm = {}
-	vm.init = function() {
-		//a running list of todos
-		vm.list = new todo.TodoList();
-		
-		//a slot to store the name of a new todo before it is created
-		vm.description = m.prop("");
-		
-		//adds a todo to the list, and clears the description field for user convenience
-		vm.add = function(description) {
-			if (description()) {
-				vm.list.push(new todo.Todo({description: description()}));
-				vm.description("");
-			}
