Mounted Feature in the vue.js.

In Vue.js, the mounted lifecycle hook is one of the lifecycle hooks provided by the framework. Lifecycle hooks are special methods that allow you to perform actions at different stages of a Vue component’s lifecycle. The mounted hook is called after the Vue instance has been mounted, i.e., the component has been inserted into the DOM.

Here’s an explanation of what happens during the mounted lifecycle hook:

1. Initialization and Compilation: Before mounted, Vue initializes the component and compiles the template. This involves creating the component’s data, methods, computed properties, and other options.
2. Render: After the initialization and compilation, Vue renders the component, converting the template and data into a virtual DOM representation.
3. Insertion into DOM: Once the virtual DOM is ready, Vue inserts the component into the actual DOM. This is the point at which the mounted hook is called.
4. Access to the DOM: In the mounted hook, you have access to the component’s DOM element, allowing you to perform actions on the DOM. This is often the stage where you might want to manipulate the DOM, set up event listeners, or perform other operations that require the component to be part of the DOM.
