»coalescelist
Function
coalescelist
takes any number of list arguments and returns the first one
that isn't empty.
»Examples
> coalescelist(["a", "b"], ["c", "d"]) [ "a", "b", ] > coalescelist([], ["c", "d"]) [ "c", "d", ]
> coalescelist(["a", "b"], ["c", "d"])
[
"a",
"b",
]
> coalescelist([], ["c", "d"])
[
"c",
"d",
]
To perform the coalescelist
operation with a list of lists, use the ...
symbol to expand the outer list as arguments:
> coalescelist([[], ["c", "d"]]...) [ "c", "d", ]
> coalescelist([[], ["c", "d"]]...)
[
"c",
"d",
]
»Related Functions
coalesce
performs a similar operation with string arguments rather than list arguments.
