The Backbone.js attributes model is used to define the property of the given model and uses the update/change the attributes using set() method.
Syntax:
Backbone.Model.attributes
Parameters: It does not accept any parameter.
Example 1: In this example, we will set the book with 1 attribute using the set() method and return 1 attribute using the get() method. The set() method performs a smart update of the collection with a set of items in the model while get() method is used to retrieve a model from a collection.
