Answer

Enums in TypeScript provide a way to define named constants that enhance code readability and maintainability. Use them when you have a fixed set of related values, such as:

  • Representing states in a state machine.
  • Defining action types in a Redux store.
  • Categorizing different user roles within an application. Having enums helps avoid magic strings and provides compile-time checks.
