Update useSize.js

[tjcchen]

Hello Kelly, thanks much for such great sharing. I notice this line of import in custom useSize hook.

import { useEffect } from "react/cjs/react.development"

Is this import intended or just a typo or something. I found in newer react versions, this line of code cast errors in my place.

Could we just use the useEffect hook from react directly.

Thanks

It may cause issues because it directly references the internal development build of React. Instead, you can use the useEffect hook directly from React itself.

@Yasin-97 Yep, that's the reason why I pull this request. Hoping the author can merge my request.
