title: Angular 2/4 : Reactive forms are synchronous while template-driven forms are asynchronous, How?
body: <p>I was going through the doc of angular.io (<a href="https://angular.io/guide/reactive-forms#async-vs-sync" rel="noreferrer">Reactive forms are synchronous</a>), trying to understand the reactive forms (how they are synchronous and template driven forms are asynchronous).</p>
  
  <p>But the doc doesn't have enough explanation with example . Can anyone help me understand how template driven forms are asynchronous and reactive forms are synchronous?</p>
  
  <p>I tried to explore a lot of blogs on the internet but didn't get an answer.</p>
  
  <p>Any help is appreciated.</p>
