### Overview

Proptics is a Profunctor Optics and Lenses library for [Scala programming language](https://scala-lang.org).

It uses a Profunctor encoding for its internal representation of optics, you can learn about profunctors in the [profunctor](https://sagifogel.github.io/Proptics/docs/profunctors/profunctor) guide.

Proptics is available for Scala 2.12, Scala 2.13, Scala 3.0, and [Scala.js](http://www.scala-js.org/),

and is built on top of [Cats](https://typelevel.org/cats/), and [Spire](https://typelevel.org/spire/).

### Getting Started
