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.

I never heard it called the Elvis operator! Thanks!
It's because if you turn it 90° to the right, it looks like Elvis' hair with two eyes underneath!
I saw it the other way, with the question mark as the curl of his lip.
Mfw I'm checking for null
?:)
Holy shit
It was called Elvis back when it was a smiley
Kotlin user spotted
php too
..but we don't talk about php
php doesn't exist, php can't hurt you
aah my favorite template engine, I have seen it so long ago

(run { [email protected]?.apply { this.value === true } } == true) ?: if (([email protected] as? Boolean) != true) false else true
Nobody's assuming Groovy these days then 😂
I've been working in Jenkins pipeline for a while now.

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:
This is equivalent:
Huh. 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
