If a value is not assigned to one of the enumerated identifiers, it's assumed that you're defining all symbols (as you're not hinting at an order or using a pooled (in memory) value). What I had thought about was this: enum { A B C } # A, B, and C become const Symbol references (Symbol('A'), Symbol('B'), Symbol('C')) enum { A = 0, B, C } # A, B, and C become const number references (0, 1, 2) enum { A, B = 'bat', C } # A, B, C become const string references ('A', 'bat', 'C') enum { A, B = 2, C = 'cat' } # becomes: const A = 'A'; const B = 2; const C = 'cat'; enum whatever { ... }; # would just become: var whatever = { ... } of course My reasoning is this: By assigning a value to any of the identifiers within an enum, you are not using the identifier as reference to a unique value (which means you don't want what Symbol has to offer). Basically if you attach a value to anything within an enum, the entire enum DOES NOT define any Symbols. If it's a number value and there are no other non-number values in the enum: we order it like a C enum. In a non-number or mixed-value enum, the identifiers default to becoming the strings they reference: enum { CAT = 3, DOG = 'whatever', FISH } # becomes: const CAT = 3; const DOG = 'whatever'; const FISH = 'FISH'; PS: disregard my lack of `let/var` _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
