Overview
Internal properties:
- $$map [JS::Object hash-bucket>] the hash table for ordinary keys
- $$smap [JS::Object hash-bucket>] the hash table for string keys
- $$keys [Array] the list of all keys
- $$proc [Proc,null,nil] the default proc used for missing keys
- hash-bucket [JS::Object] an element of a linked list that holds hash values, keys are
{key:,key_hash:,value:,next:}
