Enumeration
Enumeration is a programming concept that defines a set of named constants, typically representing a fixed list of possible values for a variable. It enhances code readability, type safety, and maintainability by replacing magic numbers or strings with meaningful identifiers. Enumerations are supported in many programming languages, often as a built-in data type or through language features.
Developers should use enumeration when dealing with a limited set of related values, such as days of the week, status codes, or configuration options, to prevent errors and improve code clarity. It is particularly useful in scenarios like state management, API design, and data validation, where explicit value definitions reduce bugs and simplify debugging.
