merge Function

merge takes an arbitrary number of maps and returns a single map that contains a merged set of elements from all of the maps.

If more than one given map defines the same key then the one that is later in the argument sequence takes precedence.

Examples

> merge({"a"="b", "c"="d"}, {"e"="f", "c"="z"})
{
  "a" = "b"
  "c" = "z"
  "e" = "f"
}
