AngularJS 2.0: A natural evolvement or a new beginning
summary
Angular 2 targets modern browsers with ES6/TypeScript, metadata annotations and web components, replacing scopes with component-based change detection that the team claims runs 3 to 10 times faster. Templates use [property] and (event) syntax; two-way binding is removed so inputs require explicit event handling (no two-way data binding). Development uses transpilers like Babel or TypeScript, dependency injection works with plain classes, and migration from Angular 1 often requires substantial rewrites (TypeScript + decorators).
