How to render array of objects in javascript react if its undefined?

I want to check for the empty array in react JavaScript. But when I am using the question mark for checking that is it undefined or not then the react and is crashing.

I am using something like this:

const [verlist, setverlist] = useState([]);

In the useEffect hook I'm using setverlist(response.versions.version). Here versions is object. And in it version is an array of objects.

But when I get versions as empty object {}, my react app crashes because in console I'm getting undefined.

I'm rendering like this:

{[...verlist].reverse().map((value, id) => {})}

How do I fix this ?
