coalesce Function

coalesce takes any number of arguments and returns the first one that isn't null or an empty string.

Examples

> coalesce("a", "b")
a
> coalesce("", "b")
b
> coalesce(1,2)

To perform the coalesce operation with a list of strings, use the ... symbol to expand the list as arguments:

> coalesce(["", "b"]...)
b
