An introduction to Purescript functions

This repository contains a small set of commented examples that illustrate how functions work in Purescript.

Setup

The code is in the Main module, which is defined in the src/Main.purs file.

To be able to play with it interactively, follow these steps:

1. While in the root folder of the project, run:

   $ spago repl
   

   This will compile the project and give you an interactive environment where you can evaluate Purescript expressions (also called a repl);

2. Import the Main module in the environment:

   > import Main
   

   Now the definitions contained in Main are available:

   > add2' 4
   6
   

If you want to modify the code, be sure to run :reload to get the latest version in the repl:

> :reload
