customers.sort(function(a,b) { 
    return new Date(a.CreatedOn).getTime() - new Date(b.CreatedOn).getTime() 
});

This will sort your array in ascending order by the field CreatedOn.

Then you can pick the last item by:

customers[customers.length - 1]

and hence set the CurrentCustomer:

customers[customers.length - 1].CurrentCustomer = true;

Use angularjs orderByFilter

function MyCtrl($scope, orderByFilter) {
$scope.customer = orderByFilter($scope. customers, 'CreatedOn')[0];
$scope.customer.CurrentCustomer=true
}

You can use libraries like Underscore, Ramda or Lodash. An example using Lodash can be found as given below and in the Link

var users = [
  { 'user': 'fred',   'age': 48 },
  { 'user': 'barney', 'age': 36 },
  { 'user': 'fred',   'age': 40 },
  { 'user': 'barney', 'age': 34 }
];

_.sortBy(users, ['user', 'age']);

An example using Ramda:

var diff = function(a, b) { return a.id > b.id; };
R.sort(diff, [
  { id: 4 },
  { id: 2 },
  { id: 7 },
  {id: 5}
]);
