title: Object spread parameter for this
body: <p>I am using dependency injection in Angular controller class (ES6)</p>
  
  <pre><code>class Ctrl{
    constructor($scope, service1, service2){
      this.$scope = $scope;
      this.service1= service1;
      this.service2= service2;
    }
  } 
  </code></pre>
  
  <p>What if i have 15 dependencies, How can i write this more elegantly in ES6/7 using spread operator or something?</p>
