What is el in Vue.js

The el(Element) attribute represents an HTML element or container in Vue.js and is used as a mount point for a Vue instance. It defines the DOM part in which the Vue instance will render.

Usage of el attribute

In Vue.js, the el attribute can be used in the following two ways:

• String selector: el can be a string selector that selects an existing HTML element as the mount point. For example:

 <code class="html"><div id="app">...</div> new Vue({ el: '#app' })</code>

• DOM element: el can also be directly a DOM element. For example:

 <code class="js">const app = document.getElementById('app'); new Vue({ el: app })</code>

Mounting process

When a Vue instance is created, Vue.js will initialize the rendering process using the mount point specified by the el property. It creates a virtual DOM based on the template and data of the Vue instance and then mounts it to the specified DOM element.

importance

The el attribute is a key attribute of a Vue instance because it determines the rendering range of the Vue instance and how it interacts with the DOM. If the el attribute is not specified, the Vue instance will not be rendered into any DOM elements.
