PureScript is a small strongly, statically typed programming language with expressive types, written in and inspired by Haskell, and compiling to JavaScript. It can be used to develop web applications, server side apps, and also desktop applications with use of Electron.
- Compile to readable JavaScript and reuse existing JavaScript code easily
- An extensive collection of libraries for development of web applications, web servers, apps and more
- Excellent tooling and editor support with instant rebuilds
- An active community with many learning resources
- Build real-world applications using functional techniques and expressive types, such as:
- Algebraic data types and pattern matching
- Row polymorphism and extensible records
- Higher kinded types
- Type classes with functional dependencies
- Higher-rank polymorphism
Here’s our recommended free books to learn PureScript.
1. PureScript by Example by Phil Freeman
PureScript is a programming language which features lightweight syntax which allows us to write very expressive code which is still clear and readable. It uses a rich type system to support powerful abstractions. It also generates fast, understandable code, which is important when interoperating with JavaScript, or other languages which compile to JavaScript.
The author seeks to convince creaders that PureScript strikes a very practical balance between the theoretical power of purely functional
programming, and the fast-and-loose programming style of JavaScript.
Chapters cover:
- Introduction.
- Getting Started
- Functions and Records.
- Recursion, Maps and Folds.
- Pattern Matching.
- Type Classes.
- Applicative Validation.
- The Eff Monad.
- Canvas Graphics.
- The Foreign Function Interface.
- Monadic Adventures.
- Callback Hell.
- Generative Testing.
- Domain-Specific Languages.

2. PureScript-Cookbook by Jordan Martinez
PureScript-Cookbook is an unofficial Cookbook for PureScript. It offers a good selection of recipes including things like how to print, create, and use values of the BigIntJs type in either the node.js or web browser console.
