The difference between mvvm and jquery

With the advancement of front-end development technology, the MVVM framework and jQuery have become tools commonly used by developers. However, there are big differences between these two tools. This article will delve into the differences, pros and cons of the MVVM framework and jQuery.

MVVM

MVVM is the abbreviation of Model-View-ViewModel. It is a front-end development framework that divides the application into three parts: model, view and view model. This development model provides a simpler and more efficient way for developers to build complex web applications more easily.

In MVVM, the model represents data and business logic, the view represents the user interface, and the view model is the bridge between the two. The view model serves as an intermediary, connecting the model and the view, while providing two-way binding capabilities. When the view model changes, both the model and the view are updated accordingly.

Advantages of the MVVM framework:

1. Compared with the traditional MVC framework, the MVVM framework provides more efficient two-way binding.
2. The separation of the MVVM framework makes the code easier to maintain and test.
3. The MVVM framework provides a simpler way to handle asynchronous and event processing.
4. The MVVM framework provides a set of standardized design patterns to make team development easier.

jQuery

jQuery is a JavaScript framework that provides developers with a more efficient and simple way to process JavaScript code.

jQuery mainly changes the dynamic effect of Web pages through selectors, DOM operations and event processing. Developers can easily implement some very popular web interactions through jQuery, such as interface animation, infinite scrolling, etc.

Advantages of jQuery framework:

1. jQuery is a very flexible framework that can quickly solve some common development problems.
2. jQuery provides powerful selectors to help developers quickly find DOM elements.
3. jQuery provides some very convenient animation and transition effects, allowing developers to easily achieve a variety of effects.
4. jQuery is a very popular framework, and developers can use a large number of plug-ins and tools to extend its functionality.

The difference between MVVM and jQuery

1. Programming paradigm

jQuery is a framework based on the imperative programming paradigm, and its design focuses on operations DOM. Developers need to pay attention to how to manipulate DOM elements to achieve interactive effects. MVVM is a framework based on the declarative programming paradigm. Developers can focus on setting the data model and view model, and the framework will automatically handle DOM operations.

2. Data flow direction

In traditional jQuery processing, developers need to manually handle the data flow direction. For example, when using jQuery to handle form input, the input values ​​need to be read and added to the form. In MVVM, when the form changes, the data is automatically bound to the data model, so that developers do not need to perform explicit operations.

3. Code Structure

In jQuery, developers need to create interdependencies between HTML and JavaScript. For example, the HTML contains a JavaScript script that handles the interaction of the page. In MVVM, data, views and view models are decoupled and each part can be tested and maintained independently.

4. Data processing

In jQuery, developers need to write a large amount of DOM manipulation code to achieve various interactive effects. In MVVM, developers can use data binding to automatically handle data changes, avoiding the complexity of manual DOM processing.

Conclusion

Although both MVVM and jQuery can be used to handle web development, there are big differences between them. The MVVM framework provides more efficient and optimized ideas, while jQuery is a more flexible and convenient framework.

Which framework to choose depends on the specific project needs and the preferences of the development team. If you want to achieve data binding and good testability, the MVVM framework will be more suitable. If you want to achieve many interface animation effects or just want to quickly deal with web development problems, then the advantages of jQuery will be even more significant.
