` DOM node is removed, React will call your the cleanup function returned from the callback.
React will also call your `ref` callback whenever you pass a *different* `ref` callback. In the above example, `(node) => { ... }` is a different function on every render. When your component re-renders, the *previous* function will be called with `null` as the argument, and the *next* function will be called with the DOM node.
#### Parameters {/*ref-callback-parameters*/}
-* `node`: A DOM node or `null`. React will pass you the DOM node when the ref gets attached, and `null` when the `ref` gets detached. Unless you pass the same function reference for the `ref` callback on every render, the callback will get temporarily detached and re-attached during every re-render of the component.
+* `node`: A DOM node. React will pass you the DOM node when the ref gets attached. Unless you pass the same function reference for the `ref` callback on every render, the callback will get temporarily cleanup and re-create during every re-render of the component.

-#### Returns {/*returns*/}
+#### React 19 added cleanup functions for `ref` callbacks. {/*react-19-added-cleanup-functions-for-ref-callbacks*/}
-* **optional** `cleanup function`: When the `ref` is detached, React will call the cleanup function. If a function is not returned by the `ref` callback, React will call the callback again with `null` as the argument when the `ref` gets detached.
+To support backwards compatibility, if a cleanup function is not returned from the `ref` callback, `node` will be called with `null` when the `ref` is detached. This behavior will be removed in a future version.
-```js
+
- {
- console.log(node);
-
- return () => {
- console.log('Clean up', node)
- }

#### Caveats {/*caveats*/}
* When Strict Mode is on, React will **run one extra development-only setup+cleanup cycle** before the first real setup. This is a stress-test that ensures that your cleanup logic "mirrors" your setup logic and that it stops or undoes whatever the setup is doing. If this causes a problem, implement the cleanup function.
-* When you pass a *different* `ref` callback, React will call the *previous* callback's cleanup function if provided. If not cleanup function is defined, the `ref` callback will be called with `null` as the argument. The *next* function will be called with the DOM node.
