Enumerated Types

[TNO]

JScript .NET introduces the enum statement that allows you to construct enumerated data types:

So my question is, what do you consider to be a good substitute for this pre-ECMA 4? An associative array?

You can limit an objects property set when you create it, and you can run an object through a sifting method to discard disallowed values before you use it,
but in javascript there is no global type enforcement-
you can always and any time add properties and values that
wouldn't be allowed in a strictly typed language.
