ng-repeat="todo in todos" creates an object called todo?

I would think of it as a forEach loop in vanilla javascript.

todos = [{
  name: 'Do the dishes',
  completed: false
  },
  {
    name: 'Do your laundry ',
    completed: true
  }]
todos.forEach(function(whatEverYouWant) {
  console.log(whatEverYouWant);
});
//=>Object {name: "Do the dishes", completed: false}
//=>Object {name: "Do your laundry ", completed: true}

<div ng-repeat="whatEverYouWant in todos">
  //Your HTML
</div>

Todos would be some array that is on your angular $scope. In ng-repeat the first part doesn't really matter what it is. You should put something that makes semantic scenes but can be what ever you want. Its just like the parameter in the forEach function. Hope that helps

The todo part is just a variable name...you could name it whatever you want. This variable will hold the value of each element of the todos array, one at a time.

"It's just a coincidence that in this project we happen to declare a todo object prior to declaring "todo in todos"?"

yeah he says that at some point in this video that he already had everything set up with todo.name or todo.completed. It was a kinda backwards way of doing it. So then when we do todo in todos, it all ties in together.
