Angular 2.0 FINAL Training
Why Angular 2?
Angular 2's Advantages
Angular 2 Is Easier
The new Angular 2 codebase is more modern, more capable and easier for new programmers to learn than Angular 1.x, while also being easier for project veterans to work with.
With Angular 1, programmers had to understand the differences between Controllers, Services, Factories, Providers and other concepts that could be confusing, especially for new programmers.
Despite being a complete rewrite, Angular 2 has retained many of its core concepts and conventions with Angular 1.x, e.g. a streamlined, "native JS" implementation of dependency injection. This means that programmers who are already proficient with Angular will have an easier time migrating to Angular 2 than another library like React or framework like Ember.
Performance and Mobile
Angular 2 was designed for mobile from the ground up. Aside from limited processing power, mobile devices have other features and limitations that separate them from traditional computers. Touch interfaces, limited screen real estate and mobile hardware have all been considered in Angular 2.
Desktop computers will also see dramatic improvements in performance and responsiveness.
Angular 2, like React and other modern frameworks, can leverage performance gains by rendering HTML on the server or even in a web worker. Depending on application/site design this isomorphic rendering can make a user's experience feel even more instantaneous.
Project Architecture and Maintenance
The first iteration of Angular provided web programmers with a highly flexible framework for developing applications. This was a dramatic shift for many web programmers, and while that framework was helpful, it became evident that it was often too flexible. Over time, best practices evolved, and a community-driven structure was endorsed.
Some of the other interesting features in Angular 2 are:
