minus-squarespartanatreyu@programming.devlinkfedilinkarrow-up1·1 year agoPretty sure they meant match as in pattern matching, not switch as in switch/case/break. You can see the proposal here: https://github.com/tc39/proposal-pattern-matching
minus-squareJakenVeina@lemm.eelinkfedilinkarrow-up0·edit-21 year agoNah, I meant switch, as that’s what it’s called in C#-land. See above. That proposal for matching looks interesting, but not quite the same, no.
minus-squarespartanatreyu@programming.devlinkfedilinkarrow-up2·edit-21 year agoAre you sure? Your C# example: var output = input switch { null => "Null", 0 => "Zero", > 0 => "Positive", _ => "Negative" }; JS proposal for match: const output = match input { when null: "Null"; when 0: "Zero"; if input > 0: "Positive"; default: "Negative"; }
