# `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"
|
||
|
|
}
|
||
|
|
```
