Can useState take async function?

TL;DR: useState is an asynchronous hook and it doesn't change the state immediately, it has to wait for the component to re-render. useRef is a synchronous hook that updates the state immediately and persists its value through the component's lifecycle, but it doesn't trigger a re-render.

Can I use async function in useEffect?

Either way, we're now safe to use async functions inside useEffect hooks. Now if/when you want to return a cleanup function, it will get called and we also keep useEffect nice and clean and free from race conditions. Enjoy using async functions with React's useEffect from here on out!

Can useState have a function?

With the useState hook, you can pass a function as an argument to initialize the state lazily.
