From the front-end-POV, I think it's also historical. Tooling used to be not so diverse just a couple of years ago, so devs got used to Notepad, TextMate, Sublime, and stick to it, because things like refactoring/testing etc. don't play a primary role. This is currently shifting due to langs like TS.

For ObjC/Swift or C# I really don't understand why someone wouldn't use an IDE. XCode and VS/VSCode are the best tools in this realm.
Agree on this too.
