What is the simplest/cleanest way to implement singleton pattern in JavaScript?...
I recently came across this article on how to write a singleton in Node.js. I know the documentation of require states that:     Modules are cached after the first time they are loaded. Multiple calls to require('foo') may not cause the mod...
Consider this pseudo code:  (function(window){    var options = { /*where everything goes */ };     var instance = (function(options){        for (var i in options){        if (options.hasOwnProperty(i)){          this[i] = options[i];        }...

tl;dr;  I need to communicate state which several services need and originates in data bound to the scope of a controller. What would a good and 'Angular zen' way to do so?  Back story  I'm developing a single page application and after m...
