How do I use enums in TypeScript classes?

You can define an enum in TypeScript and use it within a class to represent a set of named constants. Would you like an example?

Yes, please provide an example of how to implement it.

Sure! Here's a simple example:

enum Color {
    Red,
    Green,
    Blue
}

class Paint {
    color: Color;

    constructor(color: Color) {
        this.color = color;
    }
}

const myPaint = new Paint(Color.Red);
console.log(myPaint.color); // Output: 0

What does the output '0' mean in this context?

In TypeScript, enums are zero-based by default. So, Color.Red corresponds to 0, Color.Green to 1, and Color.Blue to 2. You can also assign specific values if needed.
