When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:
const Article = require('../../../../app/models/article');
Those suck for maintenance and they're ugly.

This article has been given a more permanent home on my blog. Also, since it was first written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.
Promises are a software abstraction that makes working with asynchronous operations much more pleasant. In the most basic definition, your code will move from continuation-passing style:
getTweetsFor("domenic", function (err, results) {
// the rest of your code goes here.
# xcode-build-bump.sh | |
# @desc Auto-increment the build number every time the project is run. | |
# @usage | |
# 1. Select: your Target in Xcode | |
# 2. Select: Build Phases Tab | |
# 3. Select: Add Build Phase -> Add Run Script | |
# 4. Paste code below in to new "Run Script" section | |
# 5. Drag the "Run Script" below "Link Binaries With Libraries" | |
# 6. Insure that your starting build number is set to a whole integer and not a float (e.g. 1, not 1.0) |
