How can I get data from a response payload <script>

问题

Let's say I have a function that runs fetch() to send an asynchronous GET request that returns a response with the following payload:

<script type="text/javascript">
    var csrfToken = "ImJmMWIxZjI0ZGRmMTA1ZGVkYWQ5NThlNThlYjM3OTYzYmRhNmRiMDAiU"
</script>

How can I access the csrfToken variable in Vue?

When I access the response body it converts that whole body into a giant string rather than running the JS and making the variable available for use.
