is there a standard in namespace capitalization for Javascript

I'm adopting a large mish-mash of Javascript / jQuery code. I'd like to move it to Backbone.js but as an intermediary, I'm trying to namespace it so that it is sligthtly more modular. I am wondering if there is a standard for namespaces for Javascript. I was going to do something like this: ``` var arc={ name:"Spock", nav:function(){ //alert('name' + this.name); obj=get_nav_obj(); get_to_api_v2(obj); } }; ``` Should arc be capitalized? I tend to see capitalized but since rest of site is in Ruby, lowercase might be more consistent. thx
