What's the difference between useRef and createRef ?

The difference between useRef and createRef in React lies primarily in their usage within different types of components and their behavior across renders.

useRef is a hook that is used within functional components. It was introduced in React version 16.8 as part of the Hooks API. When you use useRef, it creates a mutable ref object that persists for the lifetime of the component. This means that the ref object retains its value across re-renders of the component, without creating a new instance each time. This is useful for storing a reference to a DOM element or for keeping any mutable value that does not trigger a re-render when updated[1][2][3].

This means that if you use createRef in a functional component, a new ref object will be created on every render, which can lead to inconsistencies and is generally not the desired behavior[1][3].
