MVUbased

MVUbased is a software development pattern that centers around three core components: Model, View, and Update. This architectural approach is commonly employed in building user interfaces for web and mobile applications. The Model represents the application's data and business logic, holding the state of the application. The View is responsible for rendering the user interface based on the current state of the Model. It is a declarative representation of the Model. The Update function takes the current Model and an action (or message) as input and produces a new Model. This process ensures that the application's state changes in a predictable and controlled manner.

The MVUbased pattern emphasizes immutability, meaning that the Model is never directly modified. Instead, the Update function creates a new Model based on the previous one and the incoming action. This immutability simplifies reasoning about application state and makes debugging easier, as the history of state changes can be tracked. Actions are typically simple data structures that describe user interactions or events. The View observes the Model and automatically re-renders whenever the Model changes, ensuring that the UI is always in sync with the application's state. This unidirectional data flow from Model to View, with state changes driven by Update, is a hallmark of the MVUbased pattern. Libraries and frameworks like Elm and Redux are prominent examples that utilize variations of the MVUbased pattern.
