      It’s a shorthand for writing this:

      variable = if (input != null) input else default

      This is equivalent:

      variable = input ?: default

      The answers confusing it with the ternary operator are wrong.

        gotacha. i’ve only ever heard them called ternaries. maybe i’m old. maybe i’m too young. definitely one of the two

          It specifically refers to this shorthand ?: that works like this:

          $value = $thing_that_could_be_truthy ?: 'fallback value';

# same as

$value = $thing_that_could_be_truthy ? $thing_that_could_be_truthy : 'fallback value';

          The condition is also the value if it is truthy
