A Guide on Implementing usePrevState in React Applications

import { usePrevState } from  "@malda/usePrevState";
import {useState} from  "react";

  

const  MyComponent = () => {
const [state, setState] = useState<number>(0);
const  prevState = usePrevState<number>(state);
return (
    <div>
	    <p>Previous Value : <strong>{prevState}</strong></p>
	    <p>Current Value : <strong>{state}</strong></p>
	    <button  onClick={() =>  setState(state + 1)}>plus</button>
	    <button  onClick={() =>  setState(state - 1)}>minus</button>
