body: <p>How to merge 2 objects with Angular 2?</p>
  
  <p>In AngularJS 1 we have the "merge" and "extend" functions:
  <a href="https://docs.angularjs.org/api/ng/function/angular.merge">https://docs.angularjs.org/api/ng/function/angular.merge</a>
  <a href="https://docs.angularjs.org/api/ng/function/angular.extend">https://docs.angularjs.org/api/ng/function/angular.extend</a></p>
  
  <p>But apparently nothing in Angular 2!</p>
  
  <p>Do you have an idea?</p>
  
  <p>Thanks!</p>
