Enumerations
Enumerations (enums) are a programming language feature that defines a set of named constant values, representing a fixed collection of related items. They provide a way to create a custom data type with a limited set of possible values, enhancing code readability, type safety, and maintainability by replacing magic numbers or strings with meaningful identifiers.
Developers should use enumerations when they need to represent a finite set of options, such as days of the week, status codes, or configuration states, to prevent errors from invalid values and make the code self-documenting. They are particularly useful in scenarios like state management, API design, and configuration handling, where explicit, type-checked constants improve reliability and reduce bugs.
