Do you prefer people to use filterNot or filter { not condition }. I missed Not in the filterNot recently in review. It is probably matter of time when I will be fine.

I prefer filterNot, I like my condition to be positive, I find them easier to understand

[Milan Hruban]

I prefer filter 100% of the time, because then I can only focus on the condition, and I don't need to "remember" if it's filter or filterNot

[Paul Woitaschek]

It depends on the intention

[Paul Woitaschek]

So if we had rps (rock paper scissors) I do:
Rocks = rps.filter it==rock
NotRocks = RPS.filterNot it==rock

[Paul Woitaschek]

But generally positive things read better

[Paul Woitaschek]

So filter it.isvalid is generally easier to understand than filterNot it.isInvalid
