# How

Interface vs Implementation
Interface as List and Maps
Implementation as as Trie

#Implementation 

## Structural Sharing Technique

When we perform one of these mutable behaviors, we will recycle, only replace what has changed.

Directed Acyclic Graph(DAG)
Model all my data as DAG? But I want to use Arrays and Objects. 

Hash -> Vector
Object -> Hash Table

So, we have a cool data structure:
#reTrieve

- Index Trie

- Hash Trie
(Hash, Array, Mapped and Trie)
