what does the print map state?

Okay, 

print join("\n", @array), "\n";

[download]
says "Stick a newline between each element in @array, return that as a string, print it, and print a newline at the end." On the other hand, 
print map {$_ . "\n"} @array;

[download]
says "Build a list whose elements are the elements of @array with "\n" appended to them, then print that list."

what perldoc can I read about the map call?

You can read about any function with perldoc -f func_name.
