Brian McKenna's talk at Compose :: Conference in Melbourne, 2016.
--
Manipulating immutable data structures can involve laborious pattern-matching and copying. Functional optics such as isos, lenses, prisms, traversals and folds help us compose data manipulations. Manipulations can include getting, setting or modifying.
This presentation will show examples of optics used in production business applications. It will start with PureScript's 'pure profunctor lenses' library, then move on to examples in the Haskell, Scala and Java optics libraries, acknowledging the increasing compromises of each.
