minus-square@[email protected]linkfedilinkEnglish3•2 years agowhy would you call it anything other than the ternary operator
minus-square@[email protected]linkfedilink3•edit-22 years 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-square@[email protected]linkfedilinkEnglish2•2 years agoThe second one isn’t valid syntax in any programming language I’m familiar with. What does it do?
minus-square@[email protected]linkfedilink4•2 years agoIt’s a shorthand for writing this: variable = if (input != null) input else default This is equivalent: variable = input ?: default
minus-square@[email protected]linkfedilink2•edit-22 years agoIt’s in Kotlin and some other languages. C# has it but there is actually A ?? B.

variable = input ?: defaultHuh. Neat feature.
