In this example, it's in parentheses, so it doesn't interfere with the string concatenation operators surrounding it.statement itself will evaluate to the string "greater than" or will evaluate to the string "less than or equal to." This is the same thing that the ternary operator is doing, only the ternary operator is more compact.

However, since I usually extract conditionals to their own methods (or at least have them at the end of my method), I pretty much never assign conditionals to variables either.Ruby supports a rich set of operators, as you'd expect from a modern language. For example, a + b is interpreted as a.+(b), where the + method in the object referred to by variable a is called with b as its argument.For each operator (+ - * / % ** & | ^ There is one more operator called Ternary Operator.If no prefix expression is used, the main Object class is used by default.Conditional ternary should be used when the operations after the if or else statements are simple enough to be put into one line.In Ruby, these sequences are created using the ".." and "..." range operators.The two-dot form creates an inclusive range, while the three-dot form creates a range that excludes the specified high value. is a special operator that takes the form of a method call to determine whether or not the passed expression is defined.It returns a description string of the expression, or nil if the expression isn't defined. Operator You call a module method by preceding its name with the module's name and a period, and you reference a constant using the module name and two colons.The :: is a unary operator that allows: constants, instance methods and class methods defined within a class or module, to be accessed from anywhere outside the class or module.You may have noticed that this looks quite un-Ruby.Complex expressions just don't belong on one line in Ruby - it's usually split up and easier to read.
