title: add dimension to multidimensional array JS
body: <p>I want to add a dimension to my multidimensional array called <code>description</code>. The objective is to go through the array, count the children and add a "parent" dimension based on the number of elements existing in <code>description</code>. But i'm currently stuck trying to append information into my array. I want to add this "parent" dimension, or at least be able to put a string into the location <code>description[x]["TimeSeries"]["parent"]</code>. Any help on how to proceed?</p>
  
  <pre><code>(function () {
   var description;
   description = {
       1: {

           TimeSeries: {
               //parent: "#hero-three",
               title: "Clients Installed"
           }
       },
