An enum is a way to define a set of named values. Enums are a way to define a set of constants that can be used throughout an application. Enums are useful when you need to define a set of values that can be used in your code.

enum Color {
  Red,
  Green,
  Blue
}

function getColorName(color: Color) {
  switch (color) {
    case Color.Red:
      return 'Red';
    case Color.Green:
      return 'Green';
    case Color.Blue:
      return 'Blue';
  }
}

console.log(getColorName(Color.Red)));

In this article, we have explored the concept of enums in TypeScript and provided examples to illustrate how they work. Enums are a powerful tool that can be used to define a set of named values. By using enums, you can write more readable, maintainable, and reusable code that is easier to debug and maintain.
