Yes by defualt objects in JS are mutable, but there are ways to mess with imutable versions. There are also ways to test if two objects are Equal down to the lowest part.
Numbers as keys and custom keys are sort of frowned on, due to not valid JSON most of the time.
Adding the type as a comment for saying the type of the object seems sort of pointless: what if the type is wrong in that var, what if the type does not exist, why make the objects bigger in memory than they have to be.
