Best practice in creating objects

1. always have one global top level namespace
  e.g. var MyCoolApp = MyCoolApp || {};

2. That is included on every page 

3.All sub modules are based on that
  But they use local vars and return in functions
  
  4. Always have a top parent moduel container
  5. components are reusable within modules

  // default props to be over ridden

    active: 0
  }

  TabList.controller = function(props) {

  TabList.view = function(state, props) {

    state.list = {
      a: props.items.map(function(item, i) {
        return {
