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

When using enums 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 enum for colors:

enum Color {
    Red,
    Green,
    Blue
}

What about string enums? How do they differ?

String enums allow you to assign string values to the enum members, which can be more descriptive. For example:

enum Direction {
    Up = 'UP',
    Down = 'DOWN',
    Left = 'LEFT',
    Right = 'RIGHT'
}

Are there any performance considerations with enums?

Enums in TypeScript are compiled to objects, so they have a small overhead. However, they are generally efficient and should not impact performance significantly.
