Options available
for grouping
//we can pass either a single property
jutil.group(arrObj,'price');
//we can pass either multiple properties as array
jutil.group(arrObj,['price','city']);for sorting
// we can pass single property
jutil.objSort(arrObj,'city');
// we can pass array of properties
jutil.objSort(arrObj,['city','state','price']);
// we can pass s properties with order as object
jutil.objSort(arrObj,{'city':1,'state':1,'price':-1});for others
// to find the size of Object
jutil.size(arrObj);
// to get chunk of array
