I was reading on Wikipedia about null coalescing operators and found this entry for Kotlin.
Kotlin uses the ‘?:’ operator.[16] This is an unusual choice of symbol, given that ?: is typically used for the Elvis operator, not null coalescing, but it was inspired by Groovy (programming language) where null is considered false.
I found the Kotlin documentation describes ?: as an Elvis Operator.
Could the Wikipedia article be worded better?
