# Ruby’s Ternary Operator

For short and concise conditional if statement, one can use the ternary operator.

A ternary operation is a n-aryoperation with n = 3.

A ternary operator is an operator that takes three arguments.

condition ? "Result if condition is true" : "Result if condition is false"
#   ^                   ^                               ^
#   |                   |                               |
#   |                   |                               |
# First argument   Second argument                Third argument

If the first argument, condition to the left of ?, evaluates to true, the second argument, to the left of :, is returned. Otherwise, the third argument, to the right of :, is returned.

Ternary operator are preferred when two possibilities of result and only one operation is returned for each possibilities. Otherwise a classif if..else statement is to be preferred.
