Redux is a general-purpose state management library that can be used with any of the above frameworks or other view libraries, but is very commonly used with the React library. As the documentation in Redux alludes, many of these state management libraries are lightweight and can be replaced by each other. [2]
The upgrade also improves layout, component, and app state management capabilities. [ 9 ] During HDC 2023, August 2023, Huawei announced HarmonyOS 4.0 improvements of ArkUI with ArkTS alongside native HarmonyOS NEXT software development using Ark Engine with ArkGraphics 2D and ArkGraphics 3D .
Google introduced Flutter for native app development. Built using Dart, C, C++ and Skia, Flutter is an open-source, multi-platform app UI framework. Prior to Flutter 2.0, developers could only target Android, iOS and the web. Flutter 2.0 released support for macOS, Linux, and Windows as a beta feature. [67]
Avalonia, originally named Perspex, [15] was first developed by Steven Kirk, with its initial commit made on 5 December 2013. The framework was conceived with the aim of creating a cross-platform UI framework, inspired by Windows Presentation Foundation (WPF).
The view model has been described as a state of the data in the model. [8] The main difference between the view model and the Presenter in the MVP pattern is that the presenter has a reference to a view, whereas the view model does not. Instead, a view directly binds to properties on the view model to send and receive updates.
Users of Stack Overflow can earn reputation points and "badges"; for example, a person is awarded 10 reputation points for receiving an "up" vote on a question or an answer to a question, [12] and can receive badges for their valued contributions, [13] which represents a gamification of the traditional Q&A website.

A class delegates state-specific behavior to its current state object instead of implementing state-specific behavior directly. This makes a class independent of how state-specific behavior is implemented. New states can be added by defining new state classes. A class can change its behavior at run-time by changing its current state object.
The state diagram from Figure 2 is an example of an extended state machine, in which the complete condition of the system (called the extended state) is the combination of a qualitative aspect—the state variable—and the quantitative aspects—the extended state variables. The obvious advantage of extended state machines is flexibility.
