best way to assign or set the keys when you map over a list is to use index
, which you can get from map
return (
<>
<ul>
{country.country.map((item, index) => {
return <li key={index}>{item.name}</li>;
})}
</ul>
</>
);

i think you have to call it to generate the uuid:
return <li key={uuidv4()}>{item.name}</li>;
