Elvis operator: Languages supporting the Elvis operator, Alternative syntaxes & Overview

In certain computer programming languages, the Elvis operator, often written ?:, is a binary operator that returns the first operand if its value is logically true (according to a language-dependent convention, in other words, a truthy value) or returns its second operand if the first operand is not true. That is, it is a short-circuit OR, which returns…
