$mount and el in Vue are used to render Vue instances into the DOM. $mount is an instance method that allows mounting and remounting at any time, while el specifies the mount target when creating an instance. Element options cannot be changed once specified.

The difference between $mount and el in Vue

Direct answer:
$mount and el are both APIs used to render Vue instances into the DOM, but they have different usage methods and scopes.

Detailed expansion:

el attribute:

• el is a Vue instance An option that specifies a DOM element that contains the Vue root element.
• When using new Vue() to create a Vue instance, you can use the el option to specify the element to be mounted.
• After the Vue instance renders, it will completely take over the el element and all its child elements.

$mount method:

• $mount is an instance method, which is used to mount the Vue instance into the specified DOM element.
• The $mount method can be called at any time, even if the Vue instance has been created.
• Unlike the el option, $mount can be called multiple times, allowing the Vue instance to be remounted on different DOM elements.

Summary:

• el is an option to specify the mount target element when creating a Vue instance.
• $mount is an instance method that can be used at any time to mount a Vue instance to a specified DOM element.
• el Once specified, fixes the mount target of the Vue instance, while $mount allows dynamic mounting and remounting.
