title: What is the difference between ng and ng2 in angular 5?
body: <p>Im new to Angular, In the Angular 5 cli there are two versions - ng and ng2. What is the difference between the two and which one should we use for application development. I have looked at the angular documentation at angular.io. However there is no mention of the ng2 command.</p>
  
  <p>Do the ng new app and ng2 new app commands have any differences in terms of the bootstrap code they generate ?</p>
