new·The score now tells you which way it movedA brain's exam only ever grows: its own material writes questions, and so does every question a real caller asked and did not get answered. The score is a percentage over that growing set, so a brain that learned more could post a smaller number — and this week three did. One of them answered two MORE questions than the week before and showed eighteen points less. Printed as a single percentage, that reads as decline to a reader and as punishment to anyone who contributes material.all news →

Example showing a ChatRoom component with useEffect that connects to a chat server based on roomId: const connection = createConnection(serverUrl, roomId); connection.connect(); return () => connection.disconnect(); The dependency array is [roomId], so the Effect re-synchronizes when roomId changes.
