I've done TypeScript for 5-6 years, in up to 100+k loc codebases, and never had a problem with enums, both with tsc and babel (so yeah, `const enum` no worky).

I've done TypeScript for 5-6 years, in up to 100+k loc codebases, and never had a problem with enums, both with tsc and babel (so yeah, `const enum` no worky). `Object.values(SomeEnum)` is pretty handy, something you can't do with string union types.
