推荐答案

Typescript 2.4 是 终于发布.在字符串枚举的支持下，我不再需要使用字符串文字，并且因为 typescript 枚举被编译为 javascript，我可以在运行时访问它们(与 数字枚举).

Typescript 2.4 is finally released. With the support of string enums I no longer have to use string literals and because typescript enums are compiled to javascript I can access them at runtime (same approach as for number enums).
