I attempted to create an incredibly simple DOM type structure with javascript or least my understanding of a DOM

/***I created this to better understand the structure DOM, 
out of curiosity does anyone know why obj.ary[0].arry[0] returns 
'Object {ary: Array[1]}' I dont understand this [1] ***/
   var obj={
       ary:[
          {ary:[{ary:[3]}
                         ]  
                                              } 
                                                  ]
                                  };

because the value of obj.ary[0].arry[0] is an array that is 1 in length. If you are using something like an alert or other function that prints a string to the screen it doesn't know how to handle the array as a string so it just prints out what it is. If you want to return the value of 3, then you need obj.ary[0].ary[0].ary[0]
