I thought this may interest some here :) some concepts can be confusing. Specially when you are used to their meaning in programming before learning English. I still remember the day I realized

String

comes from a "cord/rope" of characters 🤯 https://twitter.com/pablisc0/status/1222171540567085057

and the metaphor goes deeper! https://en.wikipedia.org/wiki/Rope_(data_structure)

honestly that coffee example just confused me more than I ever was about

filter

Initially I used to think the filter operation filters out rather than filter in. So I used to think that the resulting collection will contain all items from the original except the ones that satisfy the filtering criteria. 🤷‍♂️

True. Should've called it

keep

and

discard

. 🙂

@curioustechizen thank you, that's exactly what happened to me 😁

Coffee example didn’t make sense to me either until Kiran explained it, makes a lot of sense now

I've never liked the name

filter

, which I still find confusing today since I'm never sure if it filters "in" or "out". I'd have preferred something like

keep

or

keepIf
