The ternary operator in Perl provides a shorthand way to write simple 'if-else' statements.It uses the '? :' characters and takes three arguments: a condition, a result if true, and a result if false.The ternary operator is useful for simple conditions, allowing you to assign values based on a condition in a concise manner.While the ternary operator can be nested for more complex conditions, readability should be prioritized, especially with intricate logic.
