Monocle

Monocle is an optics library for Scala and Scala.js, strongly inspired by Haskell Lens. It provides functionalities for creating and manipulating lenses, prisms, and isomorphisms. Monocle uses macros to simplify the generation of optics, such as lenses for case classes, prisms for subclasses, and isomorphisms between types. This makes it easier to work with nested data structures and perform operations like accessing, modifying, and transforming data in a concise and type-safe manner.
