Why would you use the FormatDate() function?

FormatDate() operates on date objects, not string objects, so it cannot modify or reformat a string into a non-standard date format.

FormatDate() converts date objects into strings, not strings into date objects; converting a string to a date requires a separate function such as ToDate().

FormatDate() accepts a date object and a format pattern string as parameters and returns the date as a formatted string, effectively converting the data type from date to string.

When a date value must be joined with other string content through concatenation, FormatDate() is required because date objects cannot be directly concatenated with strings without first converting them to string type.
