I could change the prints to concatenation and reformat the whole thing as a single line, so it only counts as one statement. Technically I cheated a little because this version doesn't look up the methods by reflection, but it doesn't make a difference in the result, and wouldn't significantly shorten the Java code. Definitely more readable than the Java. The JavaScript is a little messier since you don't have multi-line string literals, GStrings, and closures are
function(it){ return it.foo; }
instead of { it.foo }
.
