Question - When the components need a single root element?
Answer -
In Vue.js 2.x version, every component must have a single root element when template has more than one element. In this case, you need to wrap the elements with a parent element.
Otherwise, it will show an error, saying that "Component template should contain exactly one root element,"
The Vue.js 3.x version facilitates that the components now can have multiple root nodes. This way of adding multiple root nodes is called as fragments.
