How do I integrate enums in TypeScript?

In TypeScript, you can define an enum using the enum keyword. For example:

enum Direction {
    Up,
    Down,
    Left,
    Right
}

This creates an enum called Direction with four possible values.

Can you show me how to use this enum in a function?

Sure! Here's an example of a function that takes a Direction enum as a parameter:

function move(direction: Direction) {
    switch (direction) {
        case Direction.Up:
            console.log('Moving up!');
            break;
        case Direction.Down:
            console.log('Moving down!');
            break;
        case Direction.Left:
            console.log('Moving left!');
            break;
        case Direction.Right:
            console.log('Moving right!');
            break;
    }
}

You can call this function with any of the enum values.

What if I want to assign specific values to the enum members?

You can assign specific values by initializing the enum members like this:

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

Now, Direction.Up will have the value 1, and so on.

Thanks! Can enums be used with strings?

Yes, TypeScript also supports string enums. Here's an example:

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

This way, each enum member is associated with a string value.
