This rule emphasizes that React Fragments should not be used when there is only one child within the component. React Fragments are a useful feature for grouping a list of children without adding extra nodes to the DOM. However, when there is only a single child, the use of Fragments is unnecessary and can lead to cluttered and confusing code.
To avoid violating this rule, remove the Fragment (<>...</>) when you have only one child in your component. Instead of wrapping a single child with a Fragment, you can return the child directly.
