x ?: y is shorthand for x != null ? x : y

  Ah, thanks for the clarification. Did not know it is supported in some languages.

  In JavaScript you can simply use the logical or operator x || y

    This is not equivalent. It will result in y if x is any falsy value (like false, empty string, or 0), not just if x is nullish.

      In which languages does ?: not work that way? For example in PHP, it works exactly like you describe.

        I think that’s exactly what the nullish ?? Operator is. You can write x ?? y Which is x !== null and x != undefined ? x : y
