Describe the problem Here says "Note: The ?: Elvis operator returns the expression that precedes it if the value isn't null and the expression that proceeds it when the value is null. It lets you write this code more idiomatically. For more information, see Elvis operator." But when you click on the link, you see that: If the expression to the left of ?: is not null, the Elvis operator returns it, otherwise it returns the expression to the right. Note that the expression on the right-hand side is evaluated only if the left-hand side is null.

@rdhpn Thank you for reaching out to us. The codelab seems to explaining the same Kotlin definition differently. Could you please explain us the issue further?
