Firefox 13+ provides an experimental implementation of the map object similar to the dict object in python. Specifications here.

It's only avaible in firefox, but it looks better than using attributes of a new Object(). Citation from the documentation :

• An Object has a prototype, so there are default keys in the map. However, this can be bypassed using map = Object.create(null).
• The keys of an Object are Strings, where they can be any value for a Map.
• You can get the size of a Map easily while you have to manually keep track of size for an Object.
