var app = angular.module("app" , []);
app.controller("MyCtrl" , function($scope){
  $scope.todos = [
    {"text" :"Learn AngularJS","done":false},{"text" :"build an app","done":false}];
  $scope.removeTodo = function(index) {
  $scope.removeTodo2 = function(todo) {
    var index = getByValue( $scope.todos,todo);
  $scope.addTodo = function(todo){
    var toDoObject = {"text":todo,"done":false};
  $scope.done = function(todo){
        if(todo == todo1)
           $scope.todos[index].done = !$scope.todos[index].done;
  function getByValue(arr, value) {

  for (var i=0, iLen=arr.length; i<iLen; i++) {

    if (arr[i].text == value) return i;
  text-decoration: line-through;
