NavLink not working as per video

The browser console returned error messages when I apply the code as shown in the video:

const NavLink = props => { <Link {...props} activeClassName="active" /> };

I've managed to fix it by wrap the link within return:

const NavLink = props => { return( <Link {...props} activeClassName="active" /> ) };

But I don't quite understand why it worked for Guil, and no one else seems to have the same issue?

Where you have the outer set of curly-braces in the first code snippet are supposed to be parentheses, denoting a JSX block:

const NavLink = props => (
    <Link {...props} activeClassName="active" />
);

Using the curly-braces right after the arrow makes a multi-line arrow function, and those need a return statement to be explicit.
