Overview

The Knockout.js is a standalone JavaScript implementation of the Model-view-viewmodel pattern with templates which helps to create rich, responsive display and editor user interfaces with a clean underlying data model.

The section of UI that updates dynamically (e.g., when an external data source changes or changing depending on the user’s actions), Knockout.js can help you implement it in a more simple and sustainable way.
