I am trying to use useRef as shown below with typescript strict set to On, but I keep getting 'Object is possibly 'undefined'.

```
  const inputRef = React.useRef();
  const updateSelectionStart = () =>
    setSelectionStart(inputRef.current.selectionStart);

```

I also tried with this:

```
const inputRef = useRef<HTMLInputElement>(null);
and
const inputRef = useRef<HTMLInputElement | null>(null);

```

And nothing.

Any suggestions about how to do it without typescript errors?
