Ternary Operator in Ruby
The ternary operator is used to return a value based on the result of a binary condition.
It takes in a binary condition as input, which makes it similar to an 'if-else' control flow block. It also, however, returns a value, behaving similar to a function.
result = binaryCondition ? valueReturnedIfTrue : valueReturnedIfFalse;
The ternary cannot be used to execute code. It must be either returned in a function, or set equal to a variable with the same data type as the returned values.
def findMaximum(a, b) #if a > b, it returns a, if not it returns b return (a > b) ? a : b end
