{file}

Dummy example of using a <React ref> This example is useless and to the end user seems functionally equivalent to <react/hello.html>{file}.

It does however serve as a good example of what react does that is useful: it provides a "clear" separation between state and render code (which becomes once again much less clear in <React function components>.

Notably, this example is insane because at:
``
<button onClick={() => {
  elem.innerHTML = (parseInt(elem.innerHTML) + 1).toString()
``
we are extracing state from some random HTML string rather than having a clean <JavaScript> variable containing that value.

In this case we managed to get away with it, but this is in general not easy/possible.
