Initial Code 
/* A similar pattern to the module pattern is the “shared singleton” — create a singleton object for an application that can be used to share properties or methods between pages or inline frames.

Here’s the start of a “my.js” script that every page or frame in an application could share: */

if (typeof parent.my != “undefined”) {
var my = parent.my; // shared singleton
} else {

var my = {};

my.something …

}

/* The “parent” bit is so that the script can be used with iframes and still
retain a reference to the same “my” instance. If a page is at the top, then parent points to itself.

Every page or frame that imports “my.js” can share properties or methods with any other page. */
