i am using react and when i tried to use map function in it,i had multiple components inside map return function.so inorder to contain i used dummy parent element and started showing the error ** Each child in a list should have a unique "key" prop**.i don't know how to include key in the dummy parent <>.will you help me out.
{
dataArray.map((item,key)=>{
return(
<>
<td key={key}>{item.country}</td>
<td key={key}>{item.city}</td>
</>
)})
}
By adding the dummy parent i am getting that error unique key.is there any way i can remove the unique key error keeping both td in the return statement
Add a key to the fragment , not to the individual <td>
s:
{
dataArray.map((item, key) => {
return (
<React.Fragment key={key}>
<td>{item.country}</td>
<td>{item.city}</td>
</React.Fragment>
);
})
}
