},

import ‘rxjs/add/operator/map’;
@Injectable()
export class HttpserviceService {

constructor(private http:Http) { }

AngularJS 2 way data binding

// any variable attached to $scope can have live representation in the view
myApp.controller('myController', function($scope){
    $scope.myAppModel = {
        firstName: 'Dave',
        occupation: 'UI Architect
    };
});

<!-- if we type in new values, they will display in real time -->
<div ng-controller="myController">
  <span> {{ myAppModel.firstName }} </span><br>
  <input type="text" name="firstName" ng-model="myAppModel.firstName">
  <span> {{ myAppModel.occupation}} </span><br>
  <input type="text" name="occupation" ng-model="myAppModel.occupation">
</div>

AngularJS currently accomplishes (view-model) data-binding via “dirty-checking”, a process of recursively comparing current data values for each $scope object with previous values to see what has changed if there has been an associated UI event or “watched” model event.

Basic comparison of jQuery and AngularJS

<!-- as a user types their name, show them their input in real time -->
<!-- the jQuery IMPERATIVE way -->
<form name="imperative">
  <label for="firstName">First name: </label>
  <input type="text" name="firstName" id="firstName">
  <span id="name-output"></span>
</form>

<script>
$(function(){
    // Notice how we must make sure the ID strings in both HTML
    // and JavaScript MUST match
    $('#firstName').keypress(function(){
        // boilerplate: retrieve a model value
        var nameValue = $('#firstName').value();
        // boilerplate: paint the model value into the view
        $('#name-output').text(nameValue);
    });
});
</script>

<!-- the AngularJS DECLARATIVE way -->
<form name="declarative">
  <label for="firstName">First name: </label>
  <!-- the next two lines create the 2-way binding between the model and view -->
  <input type="text" name="firstName" id="firstName" ng-model="firstName">
  <span>{{firstName}}</span>
</form>

<script>
// Because AngularJS hides the boilerplate, no DOM string references to maintain
// between HTML and JavaScript
</script>
