I don't understand this. Small brained users rise up
On the left you have Elvis Presley, while on the right there's the so-called Elvis operator
why would you call it anything other than the ternary operator
Because 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.
The second one isn't valid syntax in any programming language I'm familiar with. What does it do?
It's a shorthand for writing this:
variable = if (input != null) input else defaultThis is equivalent:
variable = input ?: defaultHuh. Neat feature. That's in C# I assume?
It's in Kotlin and some other languages. C# has it but there it's actually
A ?? B.
Read further down on my other comment to understand, it's just how the operator looks
