Using Lodash inside of Angular

controller.js

angular.module('myModule', [ ], function($rootScope){ // equivalent to .config(function($rootScope){ . . . })
    $rootScope._ = _; // Make `_` available in Angular Expressions
}).controller('MyController', function(Something){
        var saveSomething = this.saveSomething = Something.save();
        
        $scope.$watch('something', _.debounce(saveSomething, 500));
        
        $scope.something = 'some value';
    })
; // END myModule
