Privatize a Group of JavaScript Functions

It’s a common problem in JavaScript: to use private functions you define them as an object. Later, when interfacing this object with some JavaScript library, you discover that several of the namespaces overlap.

While there is certainly some debate as to how to write an unobtrusive set of JavaScript functions, the most elegant solution is as always very simple. Basically, you wrap the set of functions in a nameless function, and then call this function immediately. The syntax we are going to use works like this:

(function(argument) {
