DRY is one of the most misunderstood practices. If you read pragmatic programmer (where DRY was coined), they make it clear that DRY doesn’t mean “avoid all repetition at all cost”. Just because two pieces of code look identical doesn’t necessarily mean they are the same. If they can grow independently of each other, then they’re not repetitions according to DRY and should be left alone.
Yup, and that is because people only ever lean DRY coding by its name. It is never really what it originally meant, when to use it and more importantly when not to use it. So loads of people apply it religiously and over use it. This is true of all the popular catchy named methodologies/principals etc.
The damning thing about DRY is that it’s so satisfying. It’s like a fun little puzzle.
