Automatically increments counter every second.
var CounterModel = Backbone.Model.extend({ defaults: { count: 0 }, increment: function() { this.set('count', this.get('count') + 1); } });
var CounterView = Backbone.View.extend({ tagName: 'div', initialize: function() { this.listenTo(this.model, 'change', this.render); this.interval = setInterval(() => this.model.increment(), 1000); }, render: function() { this.el.innerHTML = '<h2>Counter: ' + this.model.get('count') + '</h2>'; return this; } });

Backbone.js is a lightweight JavaScript MVC framework that provides structure to web applications using Models, Collections, Views, and Events. It helps developers build organized, maintainable SPAs with minimal boilerplate and strong conventions.
Primary Use Cases
- ▸Single-page applications with light structure
- ▸Legacy jQuery-based frontends
- ▸Apps requiring minimal dependencies
- ▸Projects needing manual control over architecture
- ▸Incrementally structuring existing codebases
Notable Features
- ▸Lightweight MVC architecture
- ▸Models with custom events
- ▸Collections for list handling
- ▸Views for UI rendering and events
- ▸RESTful JSON syncing with servers
Origin & Creator
Created by Jeremy Ashkenas (also creator of Underscore.js and CoffeeScript) and released by DocumentCloud in 2010.
Industrial Note
Backbone is great for small-to-medium-scale web apps, legacy systems, low-dependency environments, and scenarios requiring simple MVC architecture with minimal overhead.
