The role of $mount() in Vue

$mount()## in Vue The # method is an important method for mounting Vue instances into DOM elements. It allows a Vue instance to bind its compiled templates and reactive data to a specified DOM element, enabling Vue to control the view state of that element.

The mounting process involves the following steps:

• Compile the template: The Vue instance compiles its template, converting the template into a JavaScript rendering function.
• Create elements: The rendering function creates DOM elements based on the compiled template.
• Binding data: The Vue instance binds its reactive data to the newly created DOM element.
• Insert into DOM: The Vue instance inserts a DOM element into the specified DOM position.

$mount() The method accepts two parameters:

• #target: Specifies where the Vue instance should be mounted. Target DOM element or selector.
• parent: (optional) Specifies the parent Vue instance. If not specified, defaults to the root Vue instance.

Example:

<code class="html"><div id="app"></div></code>

<code class="js">const app = new Vue({
  el: '#app',
  data: {
    message: 'Hello Vue!'
  }
});

app.$mount();</code>

In this example, the

app instance is mounted to the #app DOM element , message Data is bound to elements responsively. When the message data changes, the DOM element automatically updates to reflect the new value.
