other people"s way of writing (without return)
export const Home = () = > {

        <div>
            <h1></h1>
            <nav>
                <Link to="/about"></Link>
                <Link to="/events"></Link>
                <Link to="/products"></Link>
                <Link to="/contact"></Link>
            </nav>
        </div>

}

what result do you expect? What is the error message actually seen?

with or without it?

are you mistaken? The arrow function is used by others. Behind the arrow is not {} but (), is equivalent to direct return ()

.
export const Home = () => (

        <div>
            <h1></h1>
            <nav>
                <Link to='/about'></Link>
                <Link to='/events'></Link>
                <Link to='/products'></Link>
                <Link to='/contact'></Link>
            </nav>
        </div>
)
