Takes two maps, creates a copy of the first map, and adds the items from the second map to the copy.
For maps with the same key, the value from the first map is replaced by the value from the second map.
For example, if you have map1 = {key1: value1} and map2 = {key1: value2},
map.merge(map1, map2) returns {key1: value2}.
