I fully agree with you. You mentioned that sometimes applying the DRY principle is a bad thing. Really, people often adhere to the DRY principle far too dogmatically.

It’s better to have some duplication than to end up with a wrong abstraction.

I like the AHA principle much more. It suggests:

  - Avoid Hasty Abstractions
  - Prefer duplication over the wrong abstraction because duplication is far cheaper than the wrong abstraction

I found it here: https://kentcdodds.com/blog/aha-programming.

The point about duplication being better than wrong abstraction is made here: https://sandimetz.com/blog/2016/1/20/the-wrong-abstraction.

And the principle doesn’t suggest avoiding abstractions altogether. It’s really only about avoiding the hasty ones. Wait with the abstraction until you feel it’s necessary or when duplication itself becomes a problem. At that point, you’ll have a clearer understanding of how the abstraction should function.
