Starting with javascript is important, it shows you the basics of object oriented programming and how a DOM can interact with HTML to edit the frontend. This principle is necessary in Django, however by using python, there is a large amount of key principles left out. Learning how types operate and why data locations should be managed by the programmer is an essential skill, but easily managed by python, for this reason, I would start with Javascript to understand how to change the front end, and then “migrate” these skills into Django only once you have learned the key OOP principles
