Models

Backbone models contain data for an application as well as the logic around this data. For example, we can use a model to represent the concept of a todo item, including its attributes like title (todo content) and completed (current state of the todo).

We can create models by extending Backbone.Model as follows:

var Todo = Backbone.Model.extend({});

// We can then create our own concrete instance of a (Todo) model
// with no values at all:
var todo1 = new Todo();
// Following logs: {}
console.log(JSON.stringify(todo1));

// or with some arbitrary data:
var todo2 = new Todo({
  title: 'Check the attributes of both model instances in the console.',
  completed: true
});

// Following logs: {"title":"Check the attributes of both model
