What does the LISTGETWITHDEFAULT function ensure?

The LISTGETWITHDEFAULT function is designed to retrieve a specific item from a list while also ensuring that it always returns a non-null value. This feature is particularly useful in scenarios where the list may not contain the requested item or might be empty. By providing a default value, the function ensures that even if the specified index or position does not have a valid entry, the function still returns a predefined default value instead of resulting in a null output. This helps maintain data integrity and prevents errors in calculations or data processing.

In this context, having the assurance of a non-null return means that users can confidently work with the output of this function without needing to manage potential null value scenarios in downstream processes.
