How is Angular pushing to 'todos?'

The last step is to push the new todo, via

$scope.todos.push(todo);

How are we pushing to todos within the scope? I just don't understand how this line of code is getting the new todo to the mock.todos.json file.

The push() here is Array.prototype.push which appends an item to the array. It won't change the mock todos.json file though. It will only add the todo to the array in memory.

What Seth said is true. The pushed "todo" (which would then be part of the "todo" array) would also be saved in a backend. This course doesn't have a real backend, in fact the json file is a static file, even tho it is a json file. The real todo app would make a POST request (ideally, it could also make a GET or PUT request) to the server that commands the database.
