// Does TypeScript enum disappear after compilation?
// Teaching excerpts; see the explanation and boundaries on the episode page.

// An enum is a runtime value.
Badge.Guest // 0
Badge[0]    // "Guest"

// Here is what the compiler adds.
var Badge;
(function (Badge) {
  Badge[Badge["Guest"] = 0] =
    "Guest";
  Badge[Badge["Boss"] = 1] =
    "Boss";
})(Badge || (Badge = {}));

// Plain object? Use as const.
const Badge = {
  Guest: 0, Boss: 1
} as const;

// JavaScript keeps:
const Badge = {
  Guest: 0, Boss: 1
};

// Choose the runtime you need.
type Badge = "guest" | "boss";
