How to extract string data from script tag, where script doesn't have any id?

Question

<script>window.extractKey = 'value'</script>

I have to extract value of window.extractKey which is present in my html source code.

P.S.- I have to extract the value using javascript methods.

All script tags on a page have, and modify, the same window. It works fine:

<script>
  window.extractKey = 'value'
</script>

<script>
  const res = window.extractKey;
  console.log(res);
</script>

I have to extract the value using javascript methods.

But why? There's literally no requirement to do so - it'll be available in any other script tag. You could select all tags, iterate through until you find one assigning that value, but...

I have a separate html file and I need to perform operation on that file and need to extract that value. That's why I need this using javascript method.
