Angular 2 is the successor of AngularJS. Those who are already familiar with Angular 2 may possibly skip this section. More information about Angular 2 can be found at the official website at the following URL: https://angular.io/. On this website, you'll find a Getting Started section, which includes a 5 MIN QuickStart guidance and a Tour of Heroes Tutorial!.
As this book is about Bootstrap, I won't discuss Angular 2 in detail, although I highly recommend you to try the QuickStart and tutorial before reading further.
We'll reuse the source code of the 5 MIN QuickStart guidance to build our own Angular 2 website with Bootstrap.
