An IDE is so much more. For instance, refactoring features. Even Microsoft defines VSCode as a "code editor" and not an IDE.
It has has debugging and task running, after all. Sounds a lot like an IDE.
It has refactoring, and revision control integrated. You can compile and run code, you can set breakpoints and step through execution. That's waaaaay more than just an editor.
I wonder what someone coming from an earlier era would have to say on that...
