Penner C Optics By Example Functional lenses in Haskell 2020 torrent

Textbook in PDF format

A comprehensive example-driven guide to Optics. Examples in Haskell, but adaptable to other languages. Become a data-manipulation wizard using Optics to manipulate data!
Lenses, also known as functional references, are a powerful way of looking at, constructing, and using functions on complex data types. They're also, unfortunately, a very new and complex subject making them challenging to learn. This book takes you from beginner to advanced using Lenses, Traversals, Prisms, and more!
Optics By Example is a one-stop comprehensive guide to mastering Optics in functional programming languages. It covers everything you need to know to go from complete beginner to advanced. Each topic is accompanied by copious examples and exercises!
What are Optics? Optics in its most general sense is a full field of study! In a slightly more concrete sense, optics are a family of tools which are interoperable with one another. Lenses, Folds, Traversals, Prisms and Isos are all types of optics which we’ll explore throughout the book! This isn’t a comprehensive list of all optics, in fact new types are still being discovered all the time! You’ll gain an intuition for what the more general concept of an optic actually is as you learn about each concrete type and begin to understand what they have in common, but to put it in a nutshell: optics are a family of inter-composable combinators for building bidirectional data transformations
