Adam 555-5678 35
Julie 555-8765 29

Mary 555-9876 19
John 555-1212 10
the example on plunker
does anyone know how to do it?

I hope this is what you are looking for:
var myApp = angular.module('myApp',[]);
function MyCtrl($scope) {
$scope.friends = [
{name:'John', phone:'555-1212', age:10},
{name:'Mary', phone:'555-9876', age:19},
{name:'Mike', phone:'555-4321', age:21},
{name:'Adam', phone:'555-5678', age:35},
{name:'Julie', phone:'555-8765', age:29}
];
$scope.change = function(o) {
var arr = [];
angular.forEach($scope.friends, function(item) {
arr.push(item[o]);
});
$scope.result = arr.sort()[0];
}
}<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="MyCtrl">
<select ng-model="val" ng-change="change(val)">
<option>name</option>
<option>phone</option>
<option>age</option>
</select>
<p>sorted first value: {{result}}</p>
</div>
orderByis to sort the entries of a collection. It has got nothing to do with finding the max and min values. You either create a custom filter that will give you the max value or simply use regular old javascript to find it yourself.
