+    Side note: the `ref` you get from `forwardRef` is mutable so you can assign to it if needed.

+
+  This was done [on purpose](https://github.com/DefinitelyTyped/DefinitelyTyped/pull/43265/). You can make it immutable if you have to - assign `React.Ref` if you want to ensure nobody reassigns it:
+
+  ```tsx
+  type Props = { children: React.ReactNode; type: "submit" | "button" };
+  export type Ref = HTMLButtonElement;
+  export const FancyButton = React.forwardRef(
+    (props: Props, ref: React.Ref<Ref>) => ( // <-- here!
+      <button ref={ref} className="MyClassName" type={props.type}>
+        {props.children}
+      </button>
+    )
+  );
+  ```
+
+</details>
+
+
 If you are grabbing the props of a component that forwards refs, use [`ComponentPropsWithRef`](https://github.com/DefinitelyTyped/DefinitelyTyped/blob/a05cc538a42243c632f054e42eab483ebf1560ab/types/react/index.d.ts#L770).
