Reverse mapping vs Object.entries

[littledan]

Is it necessary to make enums enumerable, rather than just calling Object.entries on them to get those [key, value] pairs? (I'm assuming that the enum values are enumerable.)

[ljharb]

Since currently it grabs ownKeys, I'd assume that enumerability is preserved?

[rauschma]

I was wondering the same thing. Since only retrieving keys and values is occasionally useful too, I’d do either:

1. MyEnum.keys(), MyEnum.values(), MyEnum.entries()
   • MyEnum[Symbol.iterator]() would still be equivalent to MyEnum.entries() (which is similar to Maps).
2. Object.keys(MyEnum), Object.values(MyEnum), Object.entries(MyEnum)

If (2) is not supported, then it may make sense to mention that in the proposal.
