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 →

ref attribute to get DOM node

To obtain the browser DOM node for a tag, declare a ref using useRef and pass it as the ref attribute. React will put the DOM node into ref.current after it has been rendered. Example: const inputRef = useRef(null); return <input ref={inputRef} />; then access with inputRef.current.
