PureScript is a small strongly typed programming language that compiles to JavaScript.

Deserializing and serializing JSON manually is a boring, error-prone way to be able to handle JSON. This example shows how you can use Generics in Purescript to automatically derive de/serializers so that once you've written your type definition, you only need a few lines of code to handle JSON.

Automatically de/serialize JSON with Purescript-Foreign-Generics

In Purescript, we can use set data structures using Purescript-Set, but many of its functions come with an Ord typeclass constraint. In this lesson, we'll learn how to understand the typeclass constraints on a function and how to create instances of typeclasses.

Use Sets with Ord Typeclass instances

Algebraic Data Types are a fundamental part of modeling data in Purescript. In this lesson, we'll look at some common methods of defining and using them.

Model problems using Algebraic Data Types (ADTs)

In this lesson, we'll see how we can get JSON decoding for free in PureScript using the Simple-JSON library. Because PureScript is a pretty powerful language, we can just declare what type we want the result to go into and get it for free!
