title: Angularjs - single vs multiple ng-app?
body: <p>I'm working on a web app. It's backended by Spring from controllers to database. Currently I handle page navigation using get methods from the Spring MVC controllers to access the pages.</p>
  
  <p>I'm planning to use angular JS to do my UI work. I've looked up examples on how to do it and it's all good but I'm not sure about something...</p>
  
  <p><strong>ng-app</strong></p>
  
  <p>1- Should I use one per app or one per page or it doesn't matter?</p>
  
  <p>2- If it doesn't matter when should I decide?</p>
  
  <p>I see examples using it on the html tag and some others using in divs but I'm not sure how to decide that maybe due a lack of understanding about the framework.</p>
