What are the advantages of vue

The advantages of vue are: 1. It can be developed in components, which greatly reduces the amount of code writing; 2. It can bind data in two directions; 3. The interface effect written using Vue.js itself is responsive. style, which enables the web page to display very beautiful effects on various devices; 4. Using routing will not refresh the page.

Vue.js is a progressive framework for building user interfaces. Unlike other heavyweight frameworks, Vue adopts a bottom-up incremental development design. Vue's core library only focuses on the view layer, and is very easy to learn and integrate with other libraries or existing projects. Vue, on the other hand, is fully capable of driving complex single-page applications developed using single-file components and libraries supported by the Vue ecosystem.

The goal of Vue.js is to enable responsive data binding and composed view components through the simplest possible API.

Like other frameworks, vue allows you to divide a web page into reusable components. Each component contains its own HTML, CSS, and JavaScript to render the corresponding place in the web page.

Advantages of vue:

Lightweight framework, easy to learn, two-way data binding, componentization, separation of data and structure, Virtual DOM, fast running speed.

As the preferred entry-level framework for front-end developers, Vue has many advantages:

• Vue.js can carry out component development, greatly reducing the amount of code writing, and developers Easier to understand.

• The most prominent advantage of Vue.js is that it can perform two-way binding of data (we will obviously feel the convenience of this feature in subsequent writing).

• The interface effect written using Vue.js itself is responsive, which enables the web page to display very beautiful effects on various devices.

• Compared with traditional pages that use hyperlinks to switch and jump pages, Vue uses routing without refreshing the page.

#Vue has two major features: responsive programming and componentization.

Responsive data binding

The responsiveness here is not the responsive layout in the @media media query, but refers to vue. js will automatically respond to changes in certain data on the page.

This is the biggest advantage of vue.js. It realizes two-way binding of data through the MVVM idea, so that developers no longer need to operate DOM objects and have more time to think about business logic.

Component-based development

Vue.js uses components to create a single-page application The various modules in are split into separate components (components). We only need to write various component tags (occupying pits) in the parent application first, and write the parameters to be passed into the component in the component tags. (Just like passing parameters to a function, this parameter is called the attribute of the component), and then write the implementation of various components (fill in the pits), and then the entire application is completed.

The advantages of component-based development: improve development efficiency, facilitate reuse, simplify debugging steps, improve the maintainability of the entire project, and facilitate collaborative development.

Virtual DOM

In traditional development, when using JQuery or native JavaScript DOM operation functions to frequently operate the DOM, the browser must constantly render new The DOM tree causes the page to look very stuck.

Virtual DOM is the English word for virtual DOM. Simply put, it is a method that can perform various calculations through JavaScript in advance to calculate and optimize the final DOM operation. Since this DOM operation is preprocessing There is no real operation of DOM, so it is called virtual DOM. Finally, the DOM operation is actually submitted after the calculation is completed, and the DOM operation changes are reflected to the DOM tree.
