Defining an implementation independent version of the global object in JavaScript

Question

I\'m trying to define the global object in JavaScript in a single line as follows:

var global = this.global || this;

The above

Answer 1

Implementation independant version is not trivial

(function (global) {
    // javascript framework
})(
   this && this.global || // ringoJS
   typeof root !== "undefined" && root || // node.js
   typeof global !== "undefined" && global || // more node.js
   typeof GLOBAL !== "undefined" && GLOBAL || // more node.js
   typeof window !== "undefined" && window || // browsers
   this // either undefined or some global default?
);

Your going to have to hard code in feature detection for every environment.
