PureScript is a small strongly, statically typed programming language with expressive types, written in and inspired by Haskell, and compiling to Javascript.

Functional programming in JavaScript has seen quite a lot of popularity recently, but large-scale application development is hindered by the lack of a disciplined environment in which to write code. PureScript aims to solve that problem by bringing the power of strongly-typed functional programming to the world of JavaScript development.

This book will show you how to get started with the PureScript programming language, from the basics (setting up a development environment) to the advanced.

Each chapter will be motivated by a particular problem, and in the course of solving that problem, new functional programming tools and techniques will be introduced. Here are some examples of problems that will be solved in this book:

Transforming data structures with maps and folds
Form field validation using applicative functors
Testing code with QuickCheck
Using the canvas
Domain specific language implementation
Working with the DOM
JavaScript interoperability
Dealing with callback hell
