    What's up with useRef hook?

    useRef returns an object with a current property. This current property gets the initial value of the argument passed to useRef hook. The reference to object will persist from render to render.

    The object returned by the useRef hook can be used as a container whose current property can store a value over the lifetime of the functional component.
