HTML "variable" to Javascript

Question

I can't comeup the terminology: what is the "answer" that the server sends to Get method? It builds the HTML document, but how it's called? Answer document?

I'm trying to find how i can get the html value (rname in this situation) to javascript. My server makes this html "welcome ... " text, but now i would need to reuse that name in javascript (at the same page).

<h1> Welcome {{rname}} </h1>

How i can assign rname to javascript variable?

I found this solution, but it seems way over complicated to just read one "variable" Passing variables from Flask to JavaScript

somewhere in your html template you can assign that value to a global js variable:

<h1> Welcome {{rname}} </h1>
<script>
  var username = {{rname}};
</script>

EDIT: to avoid conflicts, since this is a global variable, you might want to give it a more unique name like global_username

It is called response and you could get variables from response by res.something. But you need to specify which technology you use for communicating with your server.
