Benchmark: Enum vs const vs string

Script Preparation code:

var MyEnum;
(function (MyEnum) {
  MyEnum[MyEnum["Unknown"] = 0] = "Unknown";
  MyEnum[MyEnum["Ok"] = 1] = "Ok";
  MyEnum[MyEnum["NotOk"] = 2] = "NotOk";
})(MyEnum || (MyEnum = {}));

var ConstEnumNumber = {
  Unknown: 0,
  Ok: 1,
  NotOk: 2
};

var ConstEnumString = {
  Unknown: "Unknown",
  Ok: "Ok",
  NotOk: "NotOk"
};

var unknownValueToCompareString = "Unknown";
var unknownValueToCompareNumber = 0;

Tests:

Compare Enum string
MyEnum.Unknown === unknownValueToCompareString;
Compare Enum number
MyEnum.Unknown === unknownValueToCompareNumber;
compare const string
ConstEnumString.Unknown === unknownValueToCompareString;
compare const number
ConstEnumString.Unknown === unknownValueToCompareNumber;
compare inline string
"Unknown" === unknownValueToCompareString;
compare inline number
0 === unknownValueToCompareNumber;
