High-order functions in JavaScript

Inspired by the @MPJME's YouTube Functional Programing series.

Why?

You learn by doing. Instead of just watching him, I decided to code along and get a feel for what he's trying to teach.

This also serves me as quick reference whenever I need a quick refresher on high-order functions.

Running This

git clone
npm install
npm run transpile-es2015

To run this in your command line:

cd .\lib\
node .\GENERATED_FILE.js

Example:

node .\example-map.js
