Which model is Vue developed on?

Vue is developed based on the MVVM pattern

Vue.js is a popular JavaScript library used to build user interfaces. Its flexibility, composability, and ease of use make Vue.js one of the favorite UI libraries for many developers today. Vue.js is developed based on the design concept of the MVC (Model-View-Controller) pattern, but it actually adopts the MVVM (Model-View-ViewModel) pattern because it is more suitable for the data binding method of Vue.js.

MVVM is a UI architecture pattern developed by Microsoft. It divides the application into three main parts: Model, View and ViewModel. The idea of ​​the MVVM pattern is to decouple the view (UI) from the data model, which can minimize the coupling of the code and allow developers to change the data model without affecting the UI. The following are the components of the MVVM (Model-View-ViewModel) pattern:

1. Model: The model is the data layer, which is usually represented by a JavaScript object. The model is the central part of data interaction with the back-end server. The model includes all data and business logic.
2. View (View): The view is the user interface layer, which is the DOM element in the application. Through the view, the user can interact with the application. Views do not contain any data or business logic.
3. View Model (ViewModel): The view model is the bridge connecting the view and the model. A ViewModel is typically represented by a JavaScript class or object that logically defines the view's behavior and properties. The view model is responsible for passing data from the model to the view and using the binding mechanism to return data from the view to the model.

The MVVM pattern in Vue.js can help developers create responsive user interfaces and automatically update DOM elements through the data binding mechanism. The template syntax in Vue.js allows developers to bind views to ViewModels and implement two-way binding of data.

In short, Vue.js is a JavaScript library based on the MVVM pattern. It establishes a clear separation between models, views and view models, and automatically updates DOM elements through a data binding mechanism to achieve high efficiency. , simple and flexible UI development.
