Lee Byron of Facebook explains how persistent immutable data structures work and how to use them in React apps with Immutable.js. He covers memoization benefits and avoiding coupling through shared mutable state.
HN points to it as a clear explanation of immutable data structures such as tries, and of the case for immutability with React and Flux.

@diegorbaquero you should watch that this video . The author spoke about performance and immutability-data structures like Directional Acyclic Graphs and Trie.
IMHO, one-way data flow + immutability competes with (beats ?) observed mutations in many use cases. See this video , and more specifically this video
I found the explanation from the Immutable JS presentation easier to understand when talking about Immutable data structures [0] [0]: this video
Lee Byron on Immutable/React/Flux: this video “I only have a minute left, which is more than enough time to build the undo stack”
For anyone interested, there's a great conference talk on this topic by Lee Byron from Facebook: this video
