import { createContainer } from "unstated-next";

function useCounter(initialState = 0) {
  let [count, setCount] = useState(initialState);
  let decrement = () => setCount(count - 1);
  let increment = () => setCount(count + 1);
  return { count, decrement, increment };
}

//Using create container? Usecounter cannot complete the organization that provides the status and the new? let Counter = createContainer(useCounter);

function CounterDisplay() {
//From the usecounter of the process, do not change the status and the new one
  let counter = Counter.useContainer();
  return (
    <div>
      <button onClick={counter.decrement}>-</button>
      <span>{counter.count}</span>
      <button onClick={counter.increment}>+</button>
    </div>
  );
}

function App() {
  return (
    <Counter.Provider>
