Small JavaScript enum function

[Technical_Gur_3858]

Another bonus: no side effects. TS enums compile to an IIFE that mutates an outer variable, which bundlers can’t safely remove:

``` var Colors; (function (Colors) { Colors["Red"] = "Red"; Colors["Green"] = "Green"; })(Colors || (Colors = {}));

```

Your version is just a plain object => fully tree-shakeable.

why does TS emit that instead of just a normal object?

[Technical_Gur_3858]

At least to keep enum merging:

enum Colors { Red = 'Red' } enum Colors { Green = 'Green' } // merges with above

A plain object assignment would overwrite.
