Is Vue underlying JavaScript?

Vue.js is a popular JavaScript framework for building dynamic web applications. It uses custom tags implemented in Vue to implement various functions in the application. Vue.js is a cross-platform framework that supports multiple browsers and mobile devices.

However, many people are asking, is the bottom layer of Vue JavaScript? The answer is yes. The underlying layer of Vue.js is JavaScript, which is created using ES6 syntax. It is a lightweight framework that can be integrated with existing development technologies. Vue.js can work with both HTML and JavaScript and relate them by implementing data-driven views.

Let’s take a look at some basic concepts of Vue.js.

1. Model: It is the data source of the application, which can be data from the server or user input.
2. View: View is the data that users see on the screen. View updates are triggered by changes in the model's data.
3. Controller: The controller includes all user input and other interactive operations, as well as methods and events that connect the model and the view.

In Vue.js, models and views are bound through directives. Directives are a common way to manipulate the DOM in Vue.js. Directives are a special style used to bind models and views.

Let’s take a look at a simple Vue.js application.

First, we need to introduce the Vue.js library.

<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>

We can then create a Vue.js instance in the HTML and bind it to a DOM element.

<div id="app">
  <p>{{ message }}</p>
</div>

Finally, we are ready to create a Vue.js instance and associate it with data.

var app = new Vue({
  el: '#app',
  data: {
    message: 'Hello, Vue!'
  }
})

In this example, we create a Vue.js instance and bind it to the DOM element "app". We also bind the data "message" to the element "p" in the view. This way, when we update the data, our view also updates.

Summary

It can be seen that the bottom layer of Vue.js is implemented by JavaScript language. By using Vue.js, we can separate data and views and connect them using directives. Vue.js is an excellent open source framework that is ideal for building dynamic web applications.
