Selecting Items via filter Filter

The built-in filter fitler can be used to select the items based on different selection criteria. The selection criteria can be indicated using an expression, a map object used to match property values, or using a function. The map and function case are exemplified below:

<!DOCTYPE html>
<html>
<head lang="en">
    <meta charset="UTF-8">
    <title></title>
    <script src="../angular/angular.min.js"></script>
    <link href="../bootstrap/css/bootstrap.css" rel="stylesheet"/>
    <link href="../bootstrap/css/bootstrap-theme.css" rel="stylesheet"/>
    <script>
        angular.module("atpModule", [])
                .controller("atpCtrl", function ($scope) {
                    $scope.selectPlayers = function (item) {
                        return (item.height == "185 cm" || item.weight == "183 lbs (83 kg)");
                    };
                });
    </script>
</head>
<body>
