Persistent - or sometimes called immutable or purely functional - data structures are getting more and more attention outside functional programming languages. For example web developers recently discovered them for programming UI in React.js etc.
In his presentation Tomáš will talk about:
* Persistent data structures - basic definition
* How to make immutable data structure from mutable one
* Where and how to use PDS (examples)
* Clojure hash tables implementation
Lighting talks about other implementation of PDS are more than welcome (immutable-js anyone?)
