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

Learn Purescript

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

PureScript has a REPL (a console you can type expressions into) called `pulp`. In this lesson, we will show how you can use `pulp` to test your modules and functions. We will use code as we would in a file, like `import`ing modules. We will also use REPL specific syntax like `:type` (or `:t` for short) to view type definitions and `:reset` to re-compile changes to our files.

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 will learn how to run Purescript with a simple log statement. We use pulp to compile Purescript down to readable javascript.

Use Purescript and pulp to make hello world

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!
