<% function 'map.merge($map1, $map2)',

returns: 'map' do %>
|
|
Returns a new map with all the keys and values from both `$map1` and `$map2`.
|
|
|
|
This can also be used to add a new value or overrwrite a value in `$map1`, by
|
|
passing a single key/value pair as `$map2`.
|
|
|
|
If both `$map1` and `$map2` have the same key, `$map2`'s value takes precedence.
|
|
|
|
All keys in the returned map that also appear in `$map1` have the same order as
|
|
in `$map1`. New keys from `$map2` appear at the end of the map.
