Vue cannot use JavaScript

JavaScript is a widely used programming language, and Vue is a front-end framework based on JavaScript. However, it cannot be said that Vue cannot use JavaScript, because Vue itself is built on JavaScript.

What is Vue?

Vue is a lightweight, easy-to-use front-end framework that uses template syntax and component development model to build user interfaces. Vue uses two-way data binding to handle the interaction between data and interface, and provides many flexible life cycle functions, allowing developers to carry out targeted development according to specific situations.

The main features of Vue are:

  • Easy to get started. Vue's syntax is very simple, and it has detailed documentation and tutorials, making it very easy to learn.
  • Flexible and convenient. Vue provides a series of APIs and component libraries that facilitate development and can be easily integrated with other libraries and frameworks.
  • Component development. Vue components the view and provides a series of life cycle functions so that developers can easily control the behavior of components.

The relationship between Vue and JavaScript

Vue uses JavaScript as its basic programming language. It can realize dynamic display and processing of data through JavaScript. In the development of Vue, we will use JavaScript to write Vue components and use Vue's API to call Vue functions.

For example, in Vue we can use JavaScript to define a component:

Vue.component('my-component', {
  template: '<div>{{ message }}</div>',
  data: function () {
    return {
      message: 'Hello Vue!'
    }
  }
})

Here we use JavaScript to define a component named my-component and use it in the component's template Use Vue's responsive data binding to display data.

In actual use, we will introduce the Vue library file in the HTML file, and then instantiate the Vue object in JavaScript to manipulate the web page content:

<div id="app">
  <my-component></my-component>
</div>
var app = new Vue({
  el: '#app'
})

Here we are in the HTML file The component my-component is applied and the Vue object is instantiated in JavaScript.

Summary

In actual development, we cannot say that Vue cannot use JavaScript, because Vue itself is based on JavaScript. Vue is closely related to JavaScript, and Vue provides many APIs and life cycle functions, making JavaScript more convenient for front-end development. Therefore, before learning Vue, we need to understand the basic syntax and usage of JavaScript. During the learning process, you need to practice more and understand the connection between Vue and JavaScript, so that you can better use Vue to develop front-end web pages.
