How to declare global variables when using the strict mode pragma

Question

It\'s considered good practice to use a self-invoking function to wrap strict mode compliant code, often called the strict mode pragma:

(function(){
  \"use stri         


        

Answer 1

IMO alternative 3 is best. But it assumes that window represents the global scope - which is true for the browser but not for other JS environments (command line, Node.js, etc.).

The following will work across the board:

(function(globals){
  "use strict";
  globals.GLOB = {};
}(this));
