There are union types for strings; and there are plain javascript objects (typed as const) if "namespace.name" syntax is desired. With these available, what is the point of enums?
Yes. Both namespaces and enums (and probably the "private" keyword on class methods) are an early addition to the language, which would have never been added if typescript from the very start aligned closely with Ecmascript.
I for one can can live without all these features and will be banning via eslint.
