Opinions are like assholes, every one has got one.
This one is mine.
Punctuation is a bikeshed. Put your semicolons, whitespace, and commas where you like them.

This is a short guide that will teach you the workflows that have been figured out by the voxel.js community for writing node modules + sharing them on NPM and Github. It is assumed that you have a basic understanding of JavaScript, github and the command line (if not you can check out an introduction to git and the command line or learn JS basics from JavaScript for Cats)
The voxel-tower repository on github contains all the example code from this guide.

function foo () { while (true) { } } | |
function bar () { return foo(); } | |
bar(); | |
