backbone.jsHow do I bind a model to a view in Backbone.js?

Backbone.js provides an easy way to bind models to views. The Backbone.View.extend() function is used to create a view and the Backbone.Model.extend() is used to create a model.

The render() method is used to bind the model to the view. This method is called when the view is instantiated.

The following example shows how to bind a model to a view:

// Create model
var Person = Backbone.Model.extend({
  defaults: {
    name: '',
    age: 0

// Create view
var PersonView = Backbone.View.extend({
  el: '#person-container',
  initialize: function() {
  render: function() {
    this.$el.html(this.model.get('name') + ' is ' + this.model.get('age') + ' years old.');

// Create model instance
var person = new Person({ name: 'John', age: 25 });

// Create view instance
var personView = new PersonView({ model: person });

The output of the above code will be: John is 25 years old.
