This is not true. You can render your javascript using a template if
you like, templates can be used to generate any textual format. A view
is simply a function that takes a request and produces a single
resource as a response.
However people don't normally dynamically generate their JS. This is
because it is not necessary, you simply include the data you want into
the HTML that the javascript will run against. You then use standard
JS methods to extract the data that you need and use it.
Eg, if you wanted to trigger an AJAX request each time someone clicked
a <li>, you might do something like this:
<ul>
<li>Hello World</li>
<li>Wibble<li>
</ul>
Your JS file may have something like this:
$('ul li').click(function(ev) {
$.getJSON( '{{ some-url }}', json_handler);
}
Obviously the "{{ some-url }}" would not work. Instead, the data can
be inserted in to the HTML element to which it refers:
<ul>
<li data-json-uri="/json/foo/bar/1">Hello World</li>
<li data-json-uri="/json/foo/bar/2">Wibble<li>
</ul>
and now the JS can be written to query that data:
$('ul li').click(function(ev) {
$.getJSON(ev.target.data('json-uri'), json_handler);
}
tl;dr - if you need data in your javascript files, insert it into the
HTML doc and extract it when you need it.
