Knockout.js

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

The question is about Knockout.js .

Answer:
Knockout.js is a front-end JavaScript framework that implements the MVVM (Model-View-ViewModel) pattern for developing data-bound browser UIs. It was popular between 2010 and 2016 for dynamic web applications but has largely been replaced by React, Vue, and Angular for new projects. Knockout.js still exists in legacy enterprise applications-particularly Microsoft-stack web products-rather than being a current choice for new front-end development in 2026.
