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())

From MDN:

The map() method creates a new array with the results of calling a provided function on every element in the calling array.

That means the map method has to be returned. So,you should change your code like this:

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

or use forEach() instead of map()
