Convention: Plurals with 's', no exceptions
English is a silly language with many special cases.
When writing code, we recommend when you plural a word, you always add an 's', with no exceptions.
This means:
- dog -> dogs
- bird -> birds
- person -> persons
- moose -> mooses
- mouse -> mouses
- sheep -> sheeps
The reasons for this convention:
- Search and replace becomes way easier!
- No variable name conflicts in cases like "sheep"
However, we do not recommend showing this form of pluralization to the user, it's purely a development convention.
