import { atom, useRecoilValue, selector } from "recoil";

// create an atom
const numberState = atom({

// then use it
function Component() {
  const [number, setNumber] = useRecoilState(numberState);

  return <button onClick={() => setNumber((num) => num + 1)}>{number}</button>;
}

// to derive an atom
const aboveFiveState = selector({

// async atom

// if you only want to read an atom
const number = useRecoilValue(numberState);

// if you only want to write to an atom
