title: Whats different between AngularJS “Responsive” calls vs good old AJAX calls?
body: <p>I was watching a free interactive course published at <a href="https://angularjs.org/">angularjs.org</a> to learn Angular, <a href="http://campus.codeschool.com/courses/shaping-up-with-angular-js/intro">Shaping up with Angular js</a>.</p>
  
  <p>On this course at the very first chapter they say, one of the main reasons to use AngularJS is, it can build “Responsive” web apps. (I know about "Responsive Design" but that's totally a different thing), and explaining it saying that, with Angular you don’t need to refresh your web page  to update it with the data getting from the web server (They tell you this, like this is brand new tech!). </p>
  
  <p>I think isn’t that the same thing we did for last 10 years using Ajax? Or is this something totally different?</p>
  
  <p>Please help me to understand this coz I'm new to AngularJS.</p>
