Perl/Basics/Boolean Logic/Statements/Golfing

The term golfing applies to condensing a boolean statement into one line. Golfing is typically used when you only need to execute one line of code for a boolean statement.

print "You are not 18 or older!\n" unless ($age >= 18);

• Is essentially the same as:

print "You are not 18 or older!\n" if ($age < 18);

• Is essentially the same as this un-golfed statement:

unless ($age >= 18) { print "You are not 18 or older!\n"; }
