Update part-6-performance-normalization.md

line 480 the original filter function returned an array notifications where !notification.read was the condition. Due to the second render of the NotificationList component allNotificationsRead is being called in useLayoutEffect and notifications.filter(notification=>!notification.read).length becomes 0. So we should return a notifications array from the filter function with the condition notifications.isNew.

This is correct as-is. The intended UX is the number of "unread" notifications are in the NavBar, not the number of "new" notifications. This should go to 0 when you click on the tab, displaying NotificationList.

I see... I didn't realize the notifications badge was not intended to be present whilst viewing the notifications, but that makes sense. Thanks for your time!
Also I enjoyed this tutorial very much!
