Enums
Enums (short for enumerations) are a programming language feature that defines a set of named constant values, typically representing a fixed collection of related options or states. They provide a way to create more readable, type-safe, and maintainable code by replacing magic numbers or strings with meaningful identifiers. Enums are commonly used to represent categories, modes, statuses, or any finite set of discrete values in software development.
Developers should learn and use enums to improve code clarity, reduce errors, and enhance type safety in their applications. They are particularly useful in scenarios like defining states (e.g., OrderStatus with values like PENDING, SHIPPED, DELIVERED), configuration options, or error codes, where using strings or integers directly can lead to typos and bugs. Enums also facilitate better documentation and IDE support, making code easier to understand and refactor.
