Struct boa::syntax::ast::node::conditional::conditional_op::ConditionalOp

pub struct ConditionalOp { /* fields omitted */ }

The conditional (ternary) operator is the only JavaScript operator that takes three operands.

This operator is the only JavaScript operator that takes three operands: a condition followed by a question mark (?), then an expression to execute if the condition is truthy followed by a colon (:), and finally the expression to execute if the condition is false. This operator is frequently used as a shortcut for the if statement.
