Note that Wren makes no guarantee about iteration order which is not necessarily the same order in which the entries were added.
<lang ecmascript>// create a new map with four entries
var capitals = {
"France": "Paris",
"Germany": "Berlin",
"Russia": "Moscow",
"Spain": "Madrid"
}
// iterate through the map and print out the key/value pairs
for (c in capitals) System.print([c.key, c.value])
System.print()
// iterate though the map and print out just the keys
for (k in capitals.keys) System.print(k)
System.print()
// iterate though the map and print out just the values
for (v in capitals.values) System.print(v)</lang>
