Enums are possibly going to end up in JS eventually - this proposal[0] is at stage 1 (i know the readme says stage 0, it looks like there is a PR to update this). Granted, that means 'under consideration' but it is a start [0]: https://github.com/tc39/proposal-enum

Const objects really are better than enums, in every way except declaration brevity. They're erasable syntax, so they work in environments that just strip types. Their emit is just what you write without the types. They can be composed in a type-safe way with standard JS operations. You can still write JS docs for values, deprecated the, mark them as internal, etc. type ValueOf<T> = T[keyof T]; const Foo = { /** * A one digit * @deprecated */ one: '1', two: '2', three: '3' } as const; type Foo = ValueOf<typeof Foo>; const Bar = { blue: 'blue', } as const; type Bar = ValueOf<typeof Bar>; // You can union enum objects: const FooOrBar = {...Foo, ...Bar}; // And get union of their values: type FooOrBar = ValueOf<typeof FooOrBar>; const doSom
