What are some use cases for enums in TypeScript?

Enums in TypeScript are useful for defining a set of named constants. They can improve code readability and maintainability.

Can you give me an example of how to use enums in a TypeScript function?

Sure! You can define an enum for colors and use it in a function like this:

enum Color {
    Red,
    Green,
    Blue
}

function getColorName(color: Color): string {
    return Color[color];
}

This function takes a Color enum and returns its name.

What are the benefits of using enums over plain constants?

Enums provide better type safety, auto-completion in IDEs, and clearer intent in your code compared to plain constants.

Are there any limitations to using enums in TypeScript?

Yes, enums can increase the bundle size if used excessively, and they are not as flexible as union types in some scenarios.
