Another namespacing pattern recommendation

[lauriro]

function ns(str, root) {
  return str.split(".").reduce(function(p, n){return p[n]=p[n]||{}}, root||this)
}

!function(self){
  self.x = 1
}(ns("myApp.util"))

!function(self){
  // dependencies
  var util = ns("myApp.util")

  self.x = util.x + 1
}(ns("myApp.other"))

I was about to suggest the same. My original Gist used Array#forEach but I've updated them to use Array#reduce after seeing @lauriro's much briefer implementation!

Includes one that is basically the same as @lauriro's implementation, as well as one that actually enforces the root namespace.
