// everyone's new favorite closure pattern:
(function(window,document,undefined){ ... })(this,this.document);

// when minified:
(function(w,d,u){ ... })(this,this.document);

// which means all uses of window/document/undefined inside the closure 
// will be single-lettered, so big gains in minification.

// it also will speed up scope chain traversal a tiny tiny little bit.

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"

Embedded Variables

The ngx_http_core_module module supports embedded variables with names matching the Apache Server variables. First of all, these are variables representing client request header fields, such as $http_user_agent, $http_cookie, and so on. Also there are other variables:

• $arg_name
  argument name in the request line

JavaScript function hoisting by example

Below are many examples of function hoisting behavior in JavaScript. Ones marked as works successfuly print 'hi!' without errors.

To play around with these examples (recommended) clone them with git and execute them with e.g. node a.js
