What is Backbone.Model?

Educative Answers Team

Models are the heart of any JavaScript application. They contain the interactive data as well as a large part of the logic surrounding it: conversions, validations, computed properties, and access control. A user can extend Backbone.Model by using various domain-specific methods. The role of the Model is to provide a basic set of functionality for managing changes in our Backbone.Model.

How to use it

We use the syntax Backbone.Model.extend to create a new model class. .extend provides Backbone.Model with relevant properties of instances and class properties such as the use of constructor, etc. Moreover, .extend sets up a prototype chain and can create an inheritance model. It’s functionality is similar to classes.


Let’s look at the example for defining chocolates in a candy shop.

  1. Declare the following sources and links to allow any user to use backbone methods and resources.
<script src= 

script src= 
<script src= 

  1. Create a new backbone model.
var Chocolate = Backbone.Model.extend();
  1. Define an instance of our model.
var choc1 = new Chocolate();
  1. Use the .set method to assign some values to variables. The variable name refers to the name of the chocolate, and Price refers to the price of the chocolate.
// set the name and price of the chocolate
choc1.set({ name: "KitKat", Price: 20});
  1. Use the .get method to get the values of variables.
// get the name and price of the choclate
var p = choc1.get("Price"); 
var n = choc1.get("name");
