Well, here’s an example.

# views.py

class SomeView(View):
   def get(self, request, *args, **kwargs):
      context = {} # put some data here
      return render(request, "pathto/jsfile.js", context)

# urls.py

urlpatterns = [
   # ...
   path("chart/js", views.SomeView.as_view(), name="js"),
   # ...
]

# template
<!-- example -->
<div>
   <canvas id="chart"></canvas>
   <script type="text/javascript" src="{% url 'js' %}"></script>
<div/>

# jsfile.js

var chart = document.getElementById("chart");

{% if some_context %}
   // do something 
{% endif %}
