x is used for map, filter, etc. a and b are used for sorts, comparisons and merges. y might be used if I'm doing multiple lambda expressions (but that means I'm in a bad place already). I have no idea why, but these are firm rules in my brain.

I've gotten used to using the singular form as in...

records.filter((record) => ...)

Not saying this way is better but it works for me.

I do this too. I hate using just x, because it's so non-descriptive.

Yes! I love using x (and xs) for functions over whatever the thing is (or things are).
