Replace Triple-state Boolean with Enumeration
Read OriginalThis article explores the problem of three-state Booleans (true, false, null) in software development, using examples from Ruby on Rails and Swift. It explains how nullable Booleans create ambiguity and potential runtime errors, then advocates for using enumerations (enums) to explicitly model states like true, false, and 'not asked' for clearer, more maintainable code.
