I think it's worth pointing out that using useCallback can actually make your app even slower and may damage performance: dmitripavlutin.com/dont-overuse-re...

So the function is still created on a re-render, it just returns the same function reference as before. Therefore I think this article may be a bit misleading to readers thinking they should always implement useCallback().
