Retrieving csrftoken value with CSRF_USE_SESSIONS enabled

Hi,

While working on turning on CSRF_USE_SESSIONS for a project, I noticed that the documentation recommends the following to retrieve the value:

```

{% csrf_token %}

<script>

const csrftoken = document.querySelector('[name=csrfmiddlewaretoken]').value;

</script>

```

I am wondering why not doing the following instead?

```

<script>

const csrftoken = "{{ csrf_token }}";

</script>

```

Is there some other security benefits I'm not thinking of?

Regards

Arthur
