Why use vue.js?

Vue.js (pronounced /vjuː/, similar to view) 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 powering complex single-page applications developed with single-file components and libraries supported by the Vue ecosystem.

Reason for using vue.js:

• Vue’s core library only focuses on the view layer

Web pages with many page elements have a huge structure. If the data and views are all mixed together in HTML like traditional development, then it will be very laborious to process them.

• Vue can make web development convenient

Because Vue.js has declarative, responsive data binding, and componentization development, and also uses Virtual DOM, a technology that sounds fancy just by looking at its name.

• Component-based development

Vue.js uses components to split various modules in a single-page application into separate modules. In the component (component), we only need to first write various component tags in the parent application (occupying pits), and write the parameters to be passed into the component in the component tag (just like passing in parameters to a function, this parameter called the properties of components), and then write the implementation of various components separately (fill in the pits), and then the entire application is completed.

• Virtual DOM

When the native JavaScript DOM operation function performs frequent operations on the DOM, the browser must constantly render new DOM tree, causing the page to look very stuck. Virtual DOM can minimize operating DOM, thus avoiding performance loss.
