Answer 1

if all you're trying to do is get the value of a single entry in a map, there's no need to loop over any collection at all. simplifying gautum's response slightly, you can get the value of a named map entry as follows:

where 'map' is the collection and 'key' is the string key for which you're trying to extract the value.
