How do I use enums in TypeScript?

Enums in TypeScript are a way to define a set of named constants. You can use them to create a collection of related values.

Can you show me an example of how to define an enum?

Sure! Here's a simple example:

enum Direction {
    Up,
    Down,
    Left,
    Right
}

This defines an enum called Direction with four possible values.

How do I use the enum values in my code?

You can use the enum values like this:

let move: Direction = Direction.Up;
console.log(move); // Output: 0

By default, enums start numbering from 0.

Can I assign custom values to the enum members?

Yes! You can assign custom values like this:

enum Direction {
    Up = 1,
    Down = 2,
    Left = 3,
    Right = 4
}
