About

Jakarta Faces is a Java MVC framework for building web application user interfaces using reusable UI components.

It offers features such as templating with Facelets, state management across requests, dependency injections, internationalization, and an API that allows defining page views purely in Java.

Knockout is a JavaScript MVVM (Model-View-ViewModel) library that helps developers create rich, desktop-like user interfaces with JavaScript and HTML.

It features declarative bindings between data and UI, observable properties with automatic dependency tracking, computed observables, a built-in templating system, and efficient incremental DOM updates.
