A better way for TypeScript Enum

A better way to define enums in Typescript

const ORDER_STATUS = {
  OPEN: 'Offen',
  ORDERED: 'Bestellt',
  CANCELED: 'Storniert'
} as const;

type OrderStatus = keyof typeof ORDER_STATUS;

function methodWithEnum(status: OrderStatus) {
    console.info(`${ORDER_STATUS[status]}: ${status}`);
}

methodWithEnum("OPEN");

In this way it is much easier to provide an enum including a potential mapping to a different value e.g. a display value.

This solution is usually considered being better, as long as enums aren’t supported by JavaScript natively.
