js-fp-koans

This repository contains a set of koans for diving into the world of functional programming in Javascript.

The aim is to impart principles from ramda and fantasy-land using a hands on approach. After this lesson, you should be familiar with most of the basic principles, (and possibly the more advanced ones).

Usage

First get the koans.

git clone https://github.com/MrRacoon/js-fp-koans.git
cd js-fp-koans

It's suggested to start from the beginning and working your way through the koans in order.

Open the koan, and read through it, and replace every instance of REPLACE with the appropriate value. Be sure to also remove the x from the beginning of each describe block.

You should check your progress as you go. Every file can be tested individually by running the corresponding test:# npm script.

For example, if you are working on 1-booleans you would run:

npm run test:1

Good luck, have fun. Lemme know if a problem is lame, or something feels missing.
