Expected to return a value in arrow; function array-callback-return. Why?

Question

I\'m having some issues understanding why I\'m getting a compile warning on this piece of my react code

fetch(\'/users\')
        .then(res => res.json())

If you don't need to mutate the array and just do the console.log() you can do data.forEach() instead. It shouldn't give you the warning. Map expects you to return a value after you've transformed the array.

fetch('/users')
        .then(res => res.json())
        .then(data => {
            data.forEach(users => {
                console.log(users);
            });
        });
