What is useRef used for?

React refs, context and custom hooks · Freshers

Model answer

useRef returns an object { current } that stays the same across renders, and changing it does not cause a re-render. Common uses: getting a DOM element (inputRef.current.focus()), and storing values that should persist without triggering rendering, such as a timer id or the previous value.
