AngularJS-Service-Filter

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

//This is a service
myApp.Factory('Data', function () {
	return {message:"I'm data from a service"}
})

//This is a filter
myApp.filter('reverse', function (Data) {
	return function (text) {
		return text.split("").reverse().join("") + Data.message;
	}
})

//This is a controllers
function FirstCntrl ($scope, Data) {
	$scope.data = Data;
}

//This is another controller
function SecondCntrl ($scope, Data) {
	$scope.data = Data;
	
	//This is a function in the controller, filter above does the same thing
	$scope.reversedMessage = function (message) {
		return message.split("").reverse().join("");
	}
