The answer of that interview question would be like :- rows in JS array should have unique key property. It'll help ReactJS to find references to the appropriate DOM nodes and update only content inside mark-up but not re-render the whole table/row.
A “key” is a special string attribute you need to include when creating lists of elements. Let’s assign a key to our list items inside numbers.map() and fix the missing key issue.
sir in the initial videos you told that we cant directly give variables we need to keep in state or in props but now you are directly kept array and done ,so can you use variables directly in some purpose ,please answer it sir....
In react required key in the list because it gives respond an indication that this item is deleted, is removed and is changed, and keys don't pass to your component as props
