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:
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.
