title: Just need JSON value without its key in nested FormArray - Angular
body: <p>I have an Angular form which gets input from a user and converts it into a JSON object.</p>
  
  <p>I need an output like this:</p>
  
  <pre><code>{"Name":"sam","age":"21","Friends":[{"Name":"bob","mobile":["123","456","789"]}]}
  </code></pre>
  
  <p>I need the JSON values without the key, inside another JSON list</p>
  
  <pre><code>"mobile":["123","456","789"] 
  </code></pre>
  
  <p>I am using Reactive forms and created a nested FormArray, by doing so, I am able to get an output like this:</p>
  
  <pre><code>{"Name":"sam","age":"21","Friends":[{"Name":"bob","mobile":"123"}]}
  </code></pre>
  
  <p>But, how do I create another nested FormArray just with the values(without key) as mentioned above?</p>
  
  <p>My component.ts</p>
  
  <pre><code>this.peopleList = this._fb.group({
    Name : '',
    age : '',
    Friends: this._fb.array([this.CreateFriendList()])
  });
  
  CreateFriendList(): FormGroup {
     return this._fb.group({
        Name: '',
        mobile : '',
     });
   }
  </code></pre>
