when i use the following i get 'undefined':
function reverseString(string) {
[...string].reverse().join('')
};
but when i use this it works:
const reverseString = (string) => [...string].reverse().join('');
why is that?

function reverseString(string) { return [...string].reverse().join(''); };
The return is implicit in the shorthand form of an arrow function.
