Here's how this works:

• Include a git_hooks/ directory in your project, with these two files (plus other hooks if you want, written in a similar style).
• Add "npm" to your devDependencies in package.json, so that the pre-commit hook can do its magic.
• Add test and lint scripts to your package.json, e.g.

    "scripts": {
        "test": "mocha",
 "lint": "jshint ./lib --show-non-errors"

Latency numbers every programmer should know

1 typical CPU instruction ..................   1 ns
L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs

SSD random read ........................ 150,000 ns = 150 µs

The Problem

In Javascript this is bound in unexpected ways. Functions, in particular, create a new 'this' and so when you want to keep a reference to an "outer" object you sometimes see the pattern:

var self = this;

as in:

var self = this;

// example function where arguments 2 and 3 are optional
function example( err, optionalA, optionalB, callback ) {

    // retrieve arguments as array
    var args = [];
    for (var i = 0; i < arguments.length; i++) {
        args.push(arguments[i]);
    }

    // first argument is the error object

Let's say you have an iOS project, and you want to use some external library, like AFNetworking. How do you integrate it?

With submodules

Add the project to your repo:

git submodule add git@github.com:AFNetworking/AFNetworking.git Vendor/AFNetworking

or something to that effect.
