minus-squareAVincentInSpace@pawb.sociallinkfedilinkEnglisharrow-up2·1 day agowhy would you call it anything other than the ternary operator
minus-squaredev_null@lemmy.mllinkfedilinkarrow-up1·edit-24 hours agoBecause it’s not one. Ternary operator is A ? B : C, Elvis operator is A ?: B. The same two characters are involved, but both the syntax and effect is different.

minus-squaredev_null@lemmy.mllinkfedilinkarrow-up2·edit-24 hours agoIt’s a shorthand for writing this: variable = if (input != null) input else default This is equivalent: variable = input ?: default The answers confusing it with the ternary operator are wrong.

minus-squareThe Cuuuuube@beehaw.orglinkfedilinkEnglisharrow-up4·2 days agogotacha. i’ve only ever heard them called ternaries. maybe i’m old. maybe i’m too young. definitely one of the two
minus-squareQuazarOmega@lemy.lollinkfedilinkarrow-up7·2 days agoIt specifically refers to this shorthand ?: that works like this: $value = $thing_that_could_be_truthy ?: 'fallback value'; # same as $value = $thing_that_could_be_truthy ? $thing_that_could_be_truthy : 'fallback value'; The condition is also the value if it is truthy
