Backbone.js

Is Backbone.js a front-end or back-end JavaScript framework?

Answer:

Backbone.js is a front-end JavaScript framework that offers structure for browser-based web applications through models, views, and collections. It was widely adopted between 2010 and 2016 but has largely been replaced by React, Vue, and Angular for new development. Backbone.js still exists in maintenance mode on legacy codebases rather than as an active choice for new frontend projects in 2026.
