I have a list of Player objects. Each Player has a score: Int. I want to calculate the total score for all players.
Can I do something like

list.reduce { ... }

directly, or do I have to use map as well, e.g.

list.map { it.score }.reduce { sum, score -> sum + score }

[Lucas Ł]

how about list.sumBy{it.score} ?

Ha! Wasn’t aware of that! Much nicer 😄
