title: Editing object with Angular reactive forms
body: <p>How do I edit an object with reactive forms? Lets' assume we have an array of objects :</p>
  
  <pre><code>people = [
  {name: "Janek", color:"blue", id: 1},
  {name: "Maciek", color:"red", id: 2},
  {name: "Ala", color:"blue", id: 3},
  ]
  </code></pre>
  
  <p>If I want to edit object's properties with Template Driven approach - it's farily easy. 
  HTML </p>
  
  <pre><code>*ngFor="let person of people" 
  </code></pre>
  
  <p>and</p>
  
  <p><code>ngModel="person.name"</code> plus <code>"person.color"</code></p>
  
  <p>How to do this with Reactive Forms, so that I don't loose Id (and other properties)?</p>
