Angular 2+ Essentials: https://goo.gl/yjQPIu • Why the need to completely re-write Angular when the first version was so successful? This video will answer that question. • Angular 2 was conceived as a complete rewrite to Angular 1 in order to fulfill the expectations of modern developers who demand blazing speed and responsiveness from their web applications. • By offering faster initial loads, improved change detection and improved rendering – Angular 2 is up to five times faster then its original build. • Angular 2 is sleeker and composes a more simplified API. Many of the original constructs have been removed in favor of easier to remember patterns for writing our code. • Angular 2 is modern. By copying the huge success of the React framework, it decided to put web components at the heart of the Angular 2. As a result, Angular apps are now much more responsive to changes in state. • The latest version of Javascript known as Ecmascript2015 or just ES2015 wasn’t around back when Angular 1 was first created. By taking advantage of some of the new features like classes, modules and decorators, Angular 2 takes building sophisticated high performing applications to a whole new level. • Angular 2 is written in Typescript, which is a superset of Javascript. I absolutely love writing my code in Typescript. And the reason is Typescript give us access to all the enhancements of ES2015 including future ES7 enhancements as well as built-in strong typing. • So what hasn’t changed between Angular v1 and v2? I’m happy to say that the core concepts are still around. And that is to help developers create Modular, Maintainable and Testable applications.
