The conditional operator is important when you want your programs to utilize correct grammar. Most prominently, when differentiatiating between plural and singular forms. So rather than "There are 1 values greater than 10," or "There is 5 value less than 20," you can use conditional operators to keep you from sounding like an idiot:
(value == 1 ? "is" : "are")
(value == 1 ? "value" : "values")
So when "value" (whatever it is) is equivalent to one (one apple, one truck, one SCV), the singular form will be chosen; when it is more (or less) than one (3 accidents, 25 bills, 0 dollars), the plural form will print.

Correctly, now: There is one value; there are 5 values.
