You are simply not thinking about this logically.
The 'html file' is a Django template. It is processed by Django's
templating engine, so template variables and tags are replaced
correctly, even within inline javascript.
The 'js file' is not a Django template. It is a static file -
presumably you are serving it via Apache or the development server's
static.serve view. Because it's not being processed by Django's
templating engine, template variables and tags are not replaced but
included as-is.
If you want to include Django variables in javascript, the way to do
it is as you did at first - have a small <script> block in your actual
template, which sets the various things you need, and the external .js
file references those.
