The difference between vue homepage loading and jq

With the continuous development and upgrading of front-end development technology, web pages are becoming more and more interactive, and the requirements for front-end development tools are also getting higher and higher. Currently, the Vue framework is a very popular choice in front-end development, and jQuery is also one of the widely used front-end tools. This article will discuss the difference between Vue homepage loading and jQuery homepage loading.

Vue is an open source JavaScript framework from China. It uses the MVVM (Model-View-ViewModel) pattern based on two-way data binding to build the user interface. Vue integrates HTML, CSS and JavaScript codes and encapsulates them into reusable components, making front-end development faster, simpler and more efficient. Vue performs very well in home page loading, mainly in the following aspects:

1. Single Page Application (SPA)

SPA refers to putting the entire application In a page, HTML content is dynamically loaded using AJAX technology. Vue can use Vue Router to build SPA, which implements routing and jumping of single-page applications.

2. Component-based development

Vue is based on the component-based development model, encapsulating each component on the page and treating it as a separate module, making the module and module They can be reused, split and combined with each other. This method can minimize the time it takes for the page to request resources from the back-end server, thereby improving the page loading speed.

3. Virtual DOM

Vue uses virtual DOM technology to render the interface, performs differential calculations through the DOM-Diff algorithm, and ultimately updates only the parts that really need to be updated, instead of Re-render the entire page. This method can greatly reduce the page refresh time and improve the user's interactive experience.

In contrast, jQuery is a lightweight JavaScript library that reduces the complexity of writing JavaScript. jQuery was originally designed to make front-end development faster, easier, and more efficient. It can easily manipulate the DOM, access and modify HTML and CSS, handle events, perform animation effects, implement AJAX, and more.

Although jQuery is fully functional, easy to use, and has powerful plug-in support, it also has some relative disadvantages in homepage loading:

1. Traditional page refresh mode

jQuery still uses the traditional page refresh mode. When loading a new page, it needs to re-request new page data from the server and completely reload the entire page, resulting in a very slow page refresh.

2. The performance is relatively low

jQuery is an encapsulation of DOM operations, and its performance is slightly lower than that of native JavaScript. As the number of elements in the page increases, jQuery's performance problems will increase. Gradually stands out because it operates on a large number of DOM elements simultaneously.

3. Lack of component-based development

jQuery lacks an actual component-based development model. Developers need to manually write a large amount of code to implement component encapsulation and reuse.

In general, Vue has obvious advantages in homepage loading, mainly in its use of new technical means, which is very suitable for building modern single-page applications, and jQuery’s design takes into account many Already missing the help of a developer with basic web development knowledge, but not good enough at handling page loading and componentized development. Of course, for different application scenarios, we need to choose appropriate development tools according to specific circumstances.
