The detailed semantics of "the" ternary operator as well as its syntax differs significantly from language to language.

If-then-else flow diagram A nested if–then–else flow diagram.

See also: the {{}} template. The #if function selects one of two alternatives based on the truth value of a test string. {{#if: test string | value if true | value if false}} As explained above, a string is considered true if it contains at least one non-whitespace character.
