minus-squareQuazarOmegalinkfedilink8•1 year 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
minus-square@dev_null@lemmy.mllinkfedilink3•edit-21 year 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.

Been programming since the 80s, ditto.
