`transpose` takes a map of lists of strings and swaps the keys and values
|
|
to produce a new map of lists of strings.
|
|
|
|
## Examples
|
|
|
|
```
|
|
> transpose({"a" = ["1", "2"], "b" = ["2", "3"]})
|
|
{
|
|
"1" = [
|
|
"a",
|
|
],
|
|
"2" = [
|
|
"a",
|
|
"b",
|
|
],
|
|
"3" = [
|
|
"b",
|
|
],
|
|
}
|
