Yeah, the notes in the infra spec around ordered maps/sets probably apply here (i.e. the right question to try to answer isn't "why is it an ordered map", but instead "why shouldn't it be an ordered map"): "Almost all cases on the web platform require an ordered set, instead of an unordered one, since interoperability requires that any developer-exposed enumeration of the set’s contents be consistent between browsers. In those cases where order is not important, we still use ordered sets; implementations can optimize based on the fact that the order is not observable." -- You are receiving this because you are subscribed to this thread.
