What are the best practices for using enum types in TypeScript?

When using enum types in TypeScript, it's best to keep them simple, use descriptive names, and avoid using them for complex logic.

Can you give me an example of a simple enum?

Sure! Here's a simple example:

enum Direction {
    Up,
    Down,
    Left,
    Right
}

This enum represents four possible directions.

What about using string enums? Are they better?

String enums can be more descriptive and are often preferred when the values need to be human-readable. For example:

enum Status {
    Active = 'ACTIVE',
    Inactive = 'INACTIVE',
    Pending = 'PENDING'
}

Are there any performance considerations with enums?

Enums in TypeScript are compiled to objects, so they can have a slight performance overhead. However, for most applications, this is negligible.
