Fun with Lambda Calculus in JS

Exploring:

$ node lambda.js

Fiddling with it (npm install first):

$ npm test

Notes:

1. These are functions all the way, so expect your stack to grow real quick! :smile: You can increase it if you want with node's parameter --stack-size=<n>, as you can see in the test npm script.

2. I cheated a bit when using named lambda abstractions (for the sake of readability)

I hope you enjoy reading it as much as I enjoyed doing it! :heart: Perhaps you could add more examples…? :smile:
