Using JS for everything from turtle soup to deez nuts was the very first time I heard Full Stack Developer. I'm not bagging on Django in the slightest. It's as big as a honking house, and has all the features. And it hums nicely when you get it wired up the way you want.
But Express and Full Stack JS. . . I mean there's a lot of value in language consistency between deriving your data and displaying it to the user.
Chrome recently added a node inspector. VSCode editor (near IDE these days) also has an inspector for node. You can have a Node console, while using Nodemon (a server code monitor for restarting), with a server output console, all from within VSCode, without having to set up a dev environment for the node executable or webserving the project.
IOW: The dev environment is simple.
A couple years ago, JS Fatigue was a thing. There were seemingly DAILY releases of frameworks, tools, etc, and each one was an increment on the last. This has settled down quite a bit. There are still quite a few different and varied tools, but this is mainly from the mindset "Do one thing, do it well". All of these tools that I have used have at least a 7/10 community and support path.
Generally speaking, the brand name JS tools are well supported and have a deep community.
On the other hand, Django . . . would you be using Python 3.6 or 2.7? (The question is sarcastic.)
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
