This talk takes advantage of reftree to observe several immutable data structures in action
and uncover their inner beauty. Having surfaced immutability’s crucial tricks,
we move our focus to lenses and zippers — handy tools that combine
the convenience of the “mutable world” with the expressiveness of functional programming.
The above talk focused on immutable data and various ways it can be manipulated.
This time I would like to take you on a journey deep inside reftree itself,
so that we can see how some of these techniques and concepts can be applied...
to produce visualizations of themselves — using one of my favorite reftree
features: animations.
