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())         


        

Answer 1

Try Changing map(() => {}) to map(() => ())

{} - Creates a code block that expects an explicit return statement.
With () - implicit return takes place.
