This week we chat with Juan Pedro Bolívar Puente (a.k.a. JuanPe) about immutable data structures, value types and more - and definitely not functional programming!

How can data types be valuable if you can't change them? How can copying huge amounts of data be cheap? How can we go beyond Object-Oriented Programming - and get concurrency almost for free - all without making moral judgements about our code?

The answers to all this and more drop out of our chat with Juan Pedro.
