Ternary operator

suggest change

Ruby has a ternary operator (?:), which returns one of two value based on if a condition evaluates as truthy: 

conditional ? value_if_truthy : value_if_falsy

value = true
value ? "true" : "false"
#=> "true"

value = false
value ? "true" : "false"
#=> "false"

it is the same as writing if a then b else c end, though the ternary is preferred

Examples: 

puts (if 1 then 2 else 3 end) # => 2

puts 1 ? 2 : 3                # => 2

x = if 1 then 2 else 3 end
puts x                        # => 2
