Ruby - Conditional or Ternary operator (?:)
The Ruby conditional or ternary operator returns one of the two values based on the value of boolean expression. It is kind of similar to the if-else statement and helps to write the if-else statements in a short way.
Syntax
#returns value1 if expression is true #returns value2 if expression is false expression ? value1 : value2
Return Value
Returns value1 if the expression is evaluated to be true, and value2 if the expression is evaluated to be false.
Example:
In the example below, the ternary operator is used to find out the maximum of two numbers.
x = 50 y = 100 #maximum of two value max = (x > y) ? x : y #displaying the result puts "Maximum value = #{max}"
The output of the above code will be:
Maximum value = 100
