Foreach syntax:
angular.forEach($scope.data, function(value, key){});

Json File:
[
   {
     "Name": "Dev2tricks",
     "Password": "developerinvention"
   },
   {
     "Name": "developerinvention",
     "Password": "Dev2tricks"
   }
]

Services.js
var app = angular.module('testModule', []);
app.controller('testController', function($scope, $http){
   $http.get('Data/info.json').then(
      function(data){
         $scope.data = data;
      }
   );
   angular.forEach($scope.data, function(value, key){
      if(value.Password == "thomasTheKing")
         console.log("username is thomas");
   });
});
I know the $scope.init = function() is causing the problem, if you check the link above everything should become clear.

Could anybody explain exactly what this code is doing?
function(genre, index) - what does the index mean?

var barsApp = angular.module('barsApp',[]);

// Create and drop in as a service factory
barsApp.factory('Venues', function(){
    // This will return the Venues object
    var Venues = {};
    // Array of objects
    Venues.list = [
        { id: 0,
            name: 'Bar One',
            genres: ['Rock','Metal','Dubstep','Electro']
        },
        { id: 1,
            name: 'Bar Two',
            genres: ['Indie','Drumstep','Dubstep','Electro']
        },
        { id: 2,
            name: 'Bar Three',
            genres: ['Rock','Metal','Thrash Metal','Heavy Metal']
        },
        { id: 3,
            name: 'Bar Four',
            genres: ['Pop','RnB','Hip Hop']
        }
    ];
    return Venues;
});
// Setup controller, provide venues model into our scope
function DevCtrl($scope, Venues){
    $scope.venue = Venues;
    $scope.availableGenres = [];
    $scope.genreFilter = null;
    
    $scope.init = function() {
        angular.forEach(Venues.list, function(genre, index){
            //Only add to the availableGenres array if it doesn't already exist
            var exists = false;
            angular.forEach($scope.availableGenres, function(avGenre, index){
                if (avGenre == genre) {
                    exists = true;
                }
            });
            if (exists === false) {
                $scope.availableGenres.push(genre);
            }
        });
    
    };

$scope.setGenreFilter = function(genre) {
        $scope.genreFilter = genre;
    };
}

View.html
<div ng-app="barsApp" ng-controller="DevCtrl" ng-init="init()">
    <ul>
        <li ng-repeat="venue in venue.list | filter:genreFilter">
        <a href="">{{venue.name}}</a></li>
        <li>total {{venue.list.length}}</li>
    </ul>
