Where is the value `editing` coming from. Or previously the value `completed` came from?

I don't understand where we are getting these values from?

In Angular you can define new variables in html without the variables having been defined in the controller. The editing variable was defined on the fly.

How does angular know the initial value for those variables defined on the fly? it seems the "todo.completed" is initialized as false since the page renders all the boxes unchecked.. is that correct?

Faris Almomen Angular knows because it's a checkbox. If it's empty, it will be false. if it's checked it will be true.
