angualarjs rich in 2 way data binding. didn't need pass scope object user in function log. available in controller updated value. initialise user scope object , try code

in html:

<form ng-submit="log()">    <input type="text" ng-model="user.firstname" />    <input type="text" ng-model="user.lastname" /> </form> 

in js

.controller ('', function ($scope){     $scope.user = {};    // declare here     $scope.log = function (){         console.log ($scope.user.firstname);      } })
