The following are the features and benefits of Angular 2:

• It supports cross-platform application development, such as high performing apps like web apps, native apps using Ionic Framework, NativeScript, React Native, and creating desktop-installed apps by accessing native OS APIs using Angular methods.
• Angular 2 inherits all the benefits of Angular 1. It replaced controllers and directives with components.
• Angular 2 was written in TypeScript and also, it enabled developers to write Angular 2 applications using TypeScript.
• Angular 2 is significantly faster than Angular 1. The new component router only loads code required to render a view that is requested. The template syntax enables a developer to quickly create views with the powerful template syntax.
• Angular 2 enables us to use shadow Document Object Model (DOM). Shadow DOM encapsulates CSS, template, and the component. This enables decoupling from the DOM of the main document.
• It is the simpler cognitive model. A lot of directives were removed in Angular 2 and this means that Angular 2 has fewer pieces and fewer moving parts so that it is easier to build larger applications with Angular 2 than with Angular 1.
