You can pass a key to fragments, but you need to use the full syntax instead of the shorthand if you want to assign a key. The shorthand syntax does not support the key attribute. Here’s how you can do it: jsx Copy code {items.map((item, index) => ( {item} Description for {item} ))} Key Points: Shorthand : Cannot take a key attribute. Full : Allows you to pass a key attribute, making it useful when iterating over a list and you need to group elements without adding extra nodes to the DOM. Using React.Fragment with a key is particularly helpful in lists where you want to avoid adding unnecessary wrapper elements but still need to uniquely identify each fragment in a list.
Very helpful sir
Thank you
Could you explain the scenario in which we need to pass key in fragment and how to do so with cose example
{items.map((item, index) => (
{item}
Description for {item}
))}
