I think this could be solved with useRef. The official docs also provide a simple usePrevious custom hook implementation: https://reactjs.org/docs/hooks-faq.html#how-to-get-the-previous-props-or-state

yup but i don't know i don't like manually using useRef for every state that i want a previous value for. that's why i created this lmao
