Best practice: single source of truth (SSOT), vs DRY (don’t repeat yourself)
Jan 24, 2021
“Single source of truth” is more meaningful than the overly simplistic “DRY”.
If two things are _supposed_ to behave similarly, then not having duplicate code makes perfect sense.
If two things just _happen_ to behave similarly (at first), it may be a hasty generalisation to immediately refactor them to use the same code.
