Snippet

useForceUpdate()

In React, A component will update whenever state is updated regardless of whether the next state is identical to the current state. So all we need to make it happen is call a setState function. Doesn't even need a value.

const useForceUpdate = () => React.useState()[1]

This can be useful when using useRef. Changes to refs won't trigger a component to update. Calling forceUpdate after setting a ref may be the trick you're looking for.
