What exactly does it mean to "mount" when using an instance of vue.js to target a DOM element? Can you explain in simple terms? For example, take a look at the following code:
This snippet creates a fresh Vue instance and "attaches" it to the HTML element with the ID of app.
const app = new Vue().$mount('#app');If the Vue instance has the el option, it will automatically "connect" to that specific element.
The process of mounting occurs at the Virtual DOM Level, which happens before any content is visible to the user.
Upon calling $mount('#app'), an 'el' parameter will be configured. This 'el' specifies the ID of the element where this instance will be "mounted".
In your template, if you have an element that you wish to serve as the mounted component, you can define it in the component declaration with "el: #app".
For reference, here is the VueJS Life-Cycle Diagram: https://v2.vuejs.org/v2/guide/instance.html#Lifecycle-Diagram

Vue mounting refers to the process of transitioning virtual DOM objects (virtual HTML elements) stored in memory into visible components on the actual DOM (real HTML elements). When Vue creates these components, it is called 'Mounting'. As the application's state changes, Vue detects user-expected changes and updates the real DOM with data changes from memory, known as an 'update'. This entire process is part of Vue Lifecycle hooks, which consists of four stages: create,mount,update, and destroyed.
Within the Vue framework, the mounted() hook stands out as a frequently employed lifecycle hook. Upon insertion of a component into the Document Object Model (DOM), Vue triggers the mounted() hook. This particular hook finds its most prevalent usage in initiating HTTP requests to fetch data for subsequent rendering within the component.
