How can I use enums with objects in TypeScript?

You can use enums in TypeScript to define a set of named constants. When combined with objects, you can create a mapping of enum values to object properties.

Can you show me a code example?

Sure! Here's a simple example:

enum Color {
    Red = 'RED',
    Green = 'GREEN',
    Blue = 'BLUE'
}

const colorCodes: { [key in Color]: string } = {
    [Color.Red]: '#FF0000',
    [Color.Green]: '#00FF00',
    [Color.Blue]: '#0000FF'
};

console.log(colorCodes[Color.Red]); // Output: #FF0000

What are the benefits of using enums?

Enums provide a way to define a set of related constants, making your code more readable and maintainable. They also help prevent errors by restricting values to a predefined set.

Are there any limitations to using enums?

Yes, enums in TypeScript are not as flexible as objects. For instance, you can't easily add new values at runtime, and they can increase the complexity of your code if overused.
