One of the goals is to make it easy to take your existing client side code and port it over. Specifically, I wanted it to integrate back into the browsers environment without any extra effort.
Pretty much, yeah. It looks the same as doing a $http() or $resource() call.
But, if all you know is javascript, and you need something done in less time than it takes to delegate or learn a new language, and you need it done with some degree of secrecy, this is your tool.
Like all tools, not for everyone or every scenario. It does suggest a way to make some of your code secret and easily reabsorb the results back into your scope.
