Angular 1 was based on the MVC architecture whereas Angular 2 is based on a components-and-services architecture. Angular 1 and Angular 2 are completely different in terms of architecture and APIs, so previous knowledge of Angular 1 is unlikely to help you much in learning Angular 2. In this chapter, we will learn Angular 2 without comparing it with Angular 1 as doing that will create confusion and is unnecessary. Even if you don't have knowledge about Angular 1, you can continue with this chapter.
We will cover the following topics:
Web components
The Angular 2 architecture
Template language
Component inputs and outputs
The component life cycle
Events
Forms
Services
And much more...
