///In old dojo the code was like
for (c = 0; c < itemList.length; c++) {
   item=itemList[c];
var itemWatch = item.watch(function(name,oldVal,newVal) {
}
}

computed:{
  clonedItems: function(){
                     return JSON.parse(JSON.stringify(this.itemList));
                  }
            },
             watch:{

                clonedItems:{
                          deep: true,
                          handler: function (val, oldVal) {


This I tried which is working fine. But to get to know what value is changed of this will be heavy computation.this array can be of 100 items and each item have 600  items where we have arrays as well.


Please  guide what is the best way to achieve the similar functionality what we have
