What do you call writing -2000 lines of code? https://www.folklore.org/StoryView.py?story=Negative_2000_Li...

I call it "LOC is a terrible metric".

Most developers add new features by modifying/adding to an existing code/repo most of the time.

Hell even when you create new project, a lot of development environments provide basic scaffolding, that you then modify (or sometimes remove 95% of).
