Vue.js is an excellent JavaScript library for front-end interface development. It is very popular because it has many outstanding features, the main ones of which are Here are a few.

1. Lightweight framework

Vue.js can automatically track dependent template expressions and calculated properties, provides MVVM data binding and a composable component system, and has simple, The flexible API makes it easier for readers to understand and get started faster.

2. Two-way data binding

Declarative rendering is the main embodiment of two-way data binding. It is also the core of Vue.js. It allows declarative rendering of data using concise template syntax. Integrate into DOM.

3. Instructions

Vue.js interacts with the page, mainly through built-in instructions. The function of the instruction is to change certain behaviors accordingly when the value of its expression changes. Applied to the DOM.

4. Componentization

Component (Component) is one of the most powerful features of Vue.js. Components can extend HTML elements, encapsulating reusable code.

In Vue, parent-child components communicate through props, one-way transmission from parent to child. The child component communicates with the parent component and notifies the parent component of data changes by triggering events. This forms a basic father-child communication model.

When the components during development have a very close relationship with HTML, JavaScript, etc., the components can be customized according to actual needs, making development more convenient and greatly reducing the amount of code writing.

The component also supports hot reload. When we make changes, the page will not be refreshed, but the component itself will be reloaded immediately, without affecting the current state of the entire application. CSS also supports hot reloading.

5. Client routing

Vue-router is the official routing plug-in of Vue.js. It is deeply integrated with Vue.js and used to build single-page applications. Vue single-page applications are based on routing and components. Routing is used to set access paths and map paths and components. Traditional pages implement page switching and jumps through hyperlinks.

6. State management

State management is actually a one-way data flow. State drives the rendering of View, and the user operates the View to generate Action, which causes the State to change, thereby causing the View to Re-render to form a separate component.

The latest release of Vue 2.X is lighter and faster than Vue 1.X. Not only is it a great improvement on Vue 1.X, it also has great performance advantages compared to other frameworks. . Vue is relatively simple to learn and easier to use.
