CODE EXAMPLE FOR TYPESCRIPT

TypeScript enum

enum Direction {
  Up = 1,
  Down,
  Left,
  Right,
}
We’ll first start off with numeric enums, which are probably more familiar if you’re coming from other languages. An enum can be defined using the enum keyword.

If we wanted, we could leave off the initializers entirely:
enum Direction {
  Up,
  Down,
  Left,
  Right,
}
  
enum Direction {
  Up = "UP",
  Down = "DOWN",
  Left = "LEFT",
  Right = "RIGHT",
}
