Since ECMAScript 2015, using the Map object could be an alternative. A Map shares some similarities with an Object and guarantees the keys order:

A Map iterates its elements in insertion order, whereas iteration order is not specified for Objects.

Consider using LinkedHashMap instead of HashMap/TreeMap for internal default implementation.
