- 1 Intro
- 2 Persistent Immutable Data Structures
- 3 Structural Sharing
- 4 Directed Acyclic Graph
- 5 reTrieve
- 6 Index Trie
- 7 Implementation as Trie, Interface as Lists and Maps!
- 8 The Hash Array Mapped Trie (HAMT) is based on the simple notion of hashing a key and storing the key in a trie based on this hash value.
- 9 Simplicity is hard work. But there's a huge payoff. The person who has a genuinely simpler system is going to be able to affect the greatest change with the least work. He's going to kick your ass.
- 10 What problems does this solve anyway?

- 25 Immutable Data is Faster
- 26 Reconciliation is pretty damn fast.
- 27 Reconciliation is slower than persistent data.
- 28 Flux stores contain mutable data.
- 29 Reconciliation is pretty damn fast?
- 30 Flux stores with immutable data!
- 31 Flux store is an identity New immutable values as time passes
- 32 Bonus: Undo is easy!
- 33 No more mutable state stockholm syndrome.
- 34 Solve problems by removing complexity.
