Just wondering for arrays is it considered a better practice to keep the var names plural?
Or I guess it depends on language?
For me, when I name a collection of things it usually ends up that using plural describes it better, but it all depends on what you are naming.
I wouldn't make a collection of cats and call it cat. That's just confusing. But if you are keeping some messages in a queue messageQueue works as a name since having the word queue implies both the direction data flows and the idea of possible plurality.
