How to cast int to enum strings in TypeScript?

To cast int to enum strings in TypeScript, we can use numbers to access the enum values unless we assign the enum to different values.

For instance, we write

export enum Type {
  Info,
  Warning,
  Error,
  Fatal,
}

const x = Type[0];

to create the Type enum.

Then we can get 'Info' by using Type[0] since the first entry of an enum has 0 assigned to it as its value by default.

Conclusion
