What are Enums in TypeScript?

Enums are a TypeScript feature that allows developers to define a collection of named constants. They make code more readable and maintainable by replacing magic numbers or strings with meaningful names. TypeScript supports numeric enums, string enums, and heterogeneous enums. Enums are commonly used to represent fixed sets of values such as user roles, application states, or status codes. They provide compile-time checking and autocomplete support, reducing errors caused by invalid values.
